Why does he keep playing with my feelings??

Well, I think you should just get him out of your life. It is true that he is the father of your children, but the fact that he keeps coming and going is not fair to them, and could hurt them even more. If you guys are just not getting along, you really should move on. If you think about it, you're just using one another (because of lonliness or whatever) to fill that "emptyness" or "need" that the two of you have, but it only lasts so long. You should really find someone that you can get along with you and your kids and won't be getting together and breaking apart all the time. If it's really what you want, you NEED to put your foot down. If you're in a relationship, stay focused on that. If he comes knocking at your door, tell him that it's over and say he needs to leave, and you want something serious. It's learning to resist your urges to be with him. Also, if he's talking to one of his ex's, then he really isn't serious about you, and you deserve better. I hope this helped!

I don't know what it is that you're asking. To me, it sounds like you know he isn't the right person for you. You got two children out of it.I think you should cut your losses, be happy you have the children and let him go.
