Jess,
I’m seeing some major red flags in your posts and I really think you should stop and evaluate whether this relationship is really going to work out. This is the second post in which you say something along the lines of running back home to America if things don’t work out because of the child (and now the EX), if you are so quick to pull out the “I’ll go home” card I’ve got to ask, why in the world are you pursuing this relationship when you’re willing to go back home if the kid and her mom are too much for you? What level of commitment do you have to this relationship if you’re so willing to run away the moment you guys have issues?
Also, and I hate to break this to you, but you decided to have a child with her the moment you started dating her ex-husband. The little girl is part of the package deal you signed up for, and you get both the good and the bad that comes with that.
My boyfriend was married for ten years and has two girls with his Ex, he absolutely loathes her, and on occasion says things like “when the girls are a few years older we won’t have to deal with her”, and I’m sure he would love for that to be the case, heck I think he would love it if she got sucked into a black hole and was never heard from again! I keep telling him that just because the girls will be older that does not mean that their mother goes away, until either he or she die they will forever be a part of each other’s lives. There will be graduations, weddings, and grandchildren someday and she will be around and will have to be dealt with every step of the way.
You have to get used to the idea that this woman is always going to be there, and so will her child and you have to find a way to deal with it, however I think that in some ways you resent the fact that he has a child and an ex, I think that this will cause you severe problems in the future, especially if you are so quick to run when things don’t go your way.
