"I'm a bit worried for his lack of character. "
That really says it all. Don't tie yourself to a weak character, it will eventually end in tears- not necessarily sex with the ex, but some other issue where he caved when he should have stood strong. Of course he has to reply when his ex speaks to him- not to would be rude- but it's _what he says_ that is in his control. And two and a half hours on the phone is way too long for what should essentially be a business-type call. He could be firm without being nasty, if he was a good man. It looks like he is still emotionally into the ex, though, if he's not willing to be firm.

colleenoz,

i don't know what to say. But i kinda don't want break up before seeing what's happening. I gave him a warning and told him what i think and he said he agrees with me and he should grow a pair.
But i did think what you have just said. Weak character is not a good thing for anything and he is rather weak when it comes to standing up to people. And as you said, sex with an ex is not my concern exactly, but these other things you mention and him saying he doesn't have a control when he does. And i did tell him that and as i said he answered he needs to grow a pair. And he said himself he feels exhausted and fear that he is gonna loose me and his daughter again in a period of few months.
I will be honest, for someone for who i am rather sure that loves me...he is not thinking of what he is saying. Talk of 2 and a half hour is an alarm and he called me after that and told me he feels bad about he talked for so long with her. And when it old him not to give out that much of information he told me "as you said...i can't help but talk with her when she talks". That tells me he is either scared of her or didn't get over it.
His ex did a lot of crap to him. They had 5 years of on-off relationship which ended up pretty badly. She broke off their engagement over text on Valentines day, she was texting him after break up to let him know she slept with someone else, and later when he would find someone else she would show up at his door to try and win him back. Later on they got a child, she accused him of domestic violence that never happened and put him 5000 pounds into debt cuz he had to go court to see his kid again.
So with saying that kind of amount of bad things happen to him caused by her...you are right, he is maybe emotional about her but more in a negative way maybe.
But tell me your opinion - you think he is emotionally into his ex? In what way?

also, colleenoz,

the thing you said about him not being emotionally over his ex...that is my fear. Because he is constantly repeating i am only thing he wants in the world but these kinda of actions with 2 and a half hours on the phone shows kind of lack of respect towards me. And i fear that there is smth unresolved about his ex and that he is maybe in some way still emotionally into her, as you said. I wouldn't say it's romantically necessarily but it could be any other kind of emotional connection.
And i am worried im gonna make a wrong judgment here. That if i do believe that he is emotionally over her that his actions will show he is scared of her or that he can't be firm.
But he has also general issue with being firm with people.
I'm thinking many things here. And i am not sure how to behave in this situation.
I'm said to him i don't want her in our private life and he agreed. But i don't want her in his private life either which is the thing im scared it's gonna happen.
It's very tricky for me to say what is exactly happening.
I understand he is scared because the judge didn't make contract about him seeing his child so he is again on her mercy will she let him see her or not. That could be his biggest fear.

No-one talks to someone they're not into for two and a half hours. If you call a business, or a school, or whatever, you say what you have to say and get off the phone. They may talk to you but you don't prolong the conversation. You only talk to friends for two and a half hours.

colleenoz,

agreed. It wasn't some formal call. She often calls him to say goodnight over phone to his daughter and then starts chatting him up. Plus she is inviting him to come down his house. And with that she has kinda free road because we are on long distance. I'm not there next to him so she feels like she can pop out or call him whenever.

*she* often calls him,
*She* has kinda free road,
*she* feels like
*she* can pop out.....

See, this is something that puzzles me, even though I've done it myself:

We blame the other person & not our partner/boyfriend/spouse.

*She* isn't the one who supposedly has a partnership-type relationship with you.

*He* is.

*He* talks to her for 2+ hours at a time, etc.

*He* makes excuses to you & keeps on talking to *his* (supposed) ex.

Throw this one back & leave him in the past.

You have your own life to live, & you'll live it better without his (her/their) sordid melodrama.

I wish you the best.

sylviatexas,

nah, i don't blame her...im aware of her intentions.
but it is his blame he doesn't put a stop on it.

so yeah...im thinking about is his "melodrama" worth it. Not only because of his ex...that's the least. But generally strenghtless, can't admit mistake, stubborn and depressed is not maybe a way to go. But that's if im cold headed.

I'll see for awhile how things turned out. What he will do, how will all this function. But he did admit he made a mistake with the phone call and told me he will put her in her place. If it does happen I'll be happy. If not, I won't be very happy.

From your description, he's no prize. And I tend to go by the philosophy of What You See is What You Get. I doubt he'll suddenly grow some and stand up to his ex more than, maybe once, to show you he can. Then it's easier to slide back to the status quo.
I'm with Sylvia, throw this one back and wait for someone better to come along.

Maaan i didn't think my situation is this horrible

Sweetie, few people in horrible relationships do, until they're on the outside looking back. Then it hits them.

I guess i really have to think about this situation from another corner. Really didn't feel this bad in this relationship. Yes, he has weaknesses but he is also very caring and trying on the other hand. I guess i just have a problem making a fast decision about this before waiting how will this function with his ex and communicating since he just literally started balancing his life with seeing kid and communicating with her and having a girlfriend. But I'm maybe wrong.
