Should I

should I have sex with my ex even though he got with a girl now? hes been with her for a month and ahalf and he still wants to have sex with me and I do to with him because I love him I've been with him for 6 1/2 years and got two kids a an almost 4 year old and a 4 month old we broke up when she was almost 2 months I would also like to know if we will end up getting back together

You MAY have sex whith him if that is good for you, but the 'YOU SHOULD' is certainly not correct. At this point of in this relationship you 'SHOULD' think only of yourself and your kids. Yes, this type of conflicts can end up with re-unification of the family, but there is no guarantee for that. In your place I would inform the other female about that you two share the interest/sex of a common male, so once you 'SHOULD' have a discussion on the situation. Maybe you can invite her. Anyways is anybody mormon in this triangel?

Dont fool yourself. Just because your ex is still having sex with you, doesnt necessarily mean they care about you or want to get back together. A relationship without commitment, is all about sex!!! You will always be uncertain about your role in his life, if your just there for him physically! Don't be afraid to say that what you two had is in the past. Just don't kid yourself because the sex brought you back; be honest with yourself because sex doesn't equal a relationship!! Most people are vulnerable after a break up. It can be easier to be hurt by someone who has moved on emotionally but stays with you sexually. Breaking up usually means that both parties see other people.
Heres something for you to think about. 'You know a guy is using you when hes unavailable for you emotionally, but available for you physically!' ! He will continue coming to you for sex...if you keep allowing him to.

No you shouldnt have sex with him. He just wants the cake as well as the icing, so he'll have 2 girls to sleep with, do you really want to sleep with someone who is having sex with someone else as well? that is gross.
Second, what makes you think he will stay faithful to you if you ever got back together? if he hasnt cheated on you already.
And last, if he wanted to be with you he would be, there would be no other girl. So he wants to be 'free' and sleep around with this other girl and still have you when eva he wants, do you really want to be his doormat? I think you can do better for yourself and for your kids.

I agree with locoluna dont be his doormat.. I know you love him and its going to be hard letting him go because you guys have been together for soo long and you guys know each other like the back of your hand but DONT DO IT... he is trying to use you and trying to have sex with 2 girl.. thats nasty.. dont you think of it?? hes doing in a another girl and then going in u.. no dont do it girl.. you r wayyy better than that.. I would find myself another man that loves me and my kids f*ck that liar.. thats what he is a liar to you and to his girlfriend..
hope thats good 4 u
