me and my boyfriend have been on off for five years it seems like we fight over the littlest issues but last year when we where at it I found out he had a another girlfriend on the side and his excuse was he thought I didn’t want to be with him anymore, plus she was pregnant now that they are broken up and we are back together it seems I get very jealous when she around and I don’t understand why he feels she should be present at his family events why cant he just pick up his son and the four of us go as a family with our son that we have together why dose he want to keep here around he keeps saying she’s no different from me that she’s part of the family to its like he wants me to accept the new life live been dealt and be a perfect step mom but I have to deal with her being around full time yes he’s wit me but its not like she’s his ex it feels like where in a monogamist relationship he brings up the past that im selfish that I even gave our son my last name but I don’t think he realizes that I didn’t even expect him to stick around this long and on top of that my son in my eyes was born wit my last name we are not married and as far as me being selfish I don’t think im selfish but I do feel like I do most of the responsibility towards my son and I know he tries to help but its not my fault that he cant play a bigger part I honestly don’t know why he’s wit me I don’t feel like he’s in love with me I feel that he sticks around for our son and I think he just wants out now its like he feel that I should put all my trust in this girl because he trust her but I don’t know her and I don’t and id rather be safe then sorry I mean I don’t want us to part but I don’t know if it will work I will ever be able to send my son with the other woman brothers or not I know I can be a great wife mother step mother but some things have a limit and I hurt easily and I don’t feel that accepting a child comes with some of the things he tries to push on me its like he’s so worried about what she wants and what he wants it doesn’t matter what I want

When a situation gets to where yours is, it's no longer about what you want. The only remnant left from your relationship is your son. While you and your ex made the choices that got you where you are today, your son had nothing to do with it.

You don't have to be the other woman's new best-friend but you should cooperate and not make waves for your son's benefit. That means allow him to visit until you see evidence that she is an unfit parent. You should not talk ugly about each other in front of the child. If you allow the battle to continue, your son becomes the rope in your tug-of-war and will suffer greatly from it.

Your fling with Mr. Wonderful is over. Find another guy that understands what the word "commitment" means and get on with your life.

I agree with Rob that the relationship is over. You are clearly not satisfied with this threesome. He has no reason to change... and when you get to the point where it's necessary to issue threats or ultimatums... well, that's the end point. As painful as it is, it's time to cut your losses, be grateful for your child, and walk away... but in a cordial way --- as Rob describes --- in the interest of the children.

And do it soon. There's no need to drag this out... it's been several years as it is.

Im the last person who should give relationship advice. Im just out of my own miserable relationship, if u can call it that. I agree. Leave. It will hurt at first, but the more time that passes, the better you will feel, and the more that you will see that you deserve much better.
