Having a hard time with my boyfriend being "friends" with his ex?

[Sarah]

My boyfriend and I have known each other for 10 years and have been together since January of this year. We moved in together in June. We get along amazingly for the most part but he is still friends with his ex that he lived with for the past 6 years. I have asked him to please stop talking to her but he is constantly posting things on her facebook page and talking to her on messenger on FB. Last week he posted a .gif from an episode of 30 Rock from an episode entitled "Let's stay together" and it was a clip called "Jenna Maroney, Master of seduction" and has the female wrapping her leg around a guys shoulder. About a month ago when I was at work, my mother went by my house to drop something off and caught the ex g/f in my house with him. When I questioned him about it he said that she came by to see the dog they used to have together (who now lives with us). I'm not buying that. My mom sat outside the house to make sure she left and she called me a few minutes later telling me they left together with the dog. He never would tell me where they went other than "to walk the dog". He says that I am trying to be controlling in telling him who he can and can't be friends with, but I don't think he needs to be talking to his ex. Am I wrong? I don't talk to any of my ex's. Another thing is he is currently unemployed and I work 12 hour night shifts, so I am paying for everything. she also recently changed her facebook profile picture to their dog, who as I said now lives with me. I feel like something is up or either she is trying to piss me off. They don't have children together so have no ties to each other. Am I in the wrong here in this situation? Is he being shady and do I have the right to be suspicious about him talking to her, or am I really controlling? What do you people think about my situation?

Personally, I would be very concerned like you are about what kind of relationship they have. I think you have every right to question him. He seems to be spending a lot of time with his ex and is a bit shady about it by not telling you what he is doing with her. I'd certainly feel jealous with the facebook post too. In my honest opinion, if he just barks at you by making you feel guilty ( IE saying your being controlling ) that's a big flag. If he was doing nothing wrong, I don't think he'd lash out like that, seems like he is getting angry that your concerned about their relationship.

I also really don't think there is anything wrong with being friends with an Ex. So long as you respect your current partner. Talking to them and hanging out with them once in a while is one thing, but all the time and then seemingly being sneaky about it is another. If you are expressing your concerns and he doesn't care, nor willing to compromise, it does seem quite fishy.

I say - If you can handle him hanging out with her once in a while then talk to him again. Let him know your not trying to be controlling, and that its OK if he wants to talk with her once in a while or hang out with her once in a while, but all the time is not okay with you, that it makes you feel uncomfortable. If he doesn't care how you feel. Move out. After all, your the one that works and pays for everything
