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?
I would especially like to get a guys point of view on this matter.

It sounds a little shady to me and I would be upset as well. Try a new approach. Ask him to not see her alone or without letting you know ahead of time. If she just stops by, ask him to call/text you to tell you so you don't have to find out from someone else. Being friends with an ex is one thing, but hanging out alone in your house together is quite disrespectful. Even if he isn't cheating on you with her, it's still not right that he is bringing her around in your house without telling you.

I'm afraid your boyfriend is lying to you. You let this relationship get serious too quickly and now he's fine to have a full time partner + sneak around with his old serious girlfriend. He's having his cake and eating it too at your expense. Forget all about what he says, the best option would be to stop discussing this because that hasn't worked, You need to pack up your stuff and move out and that will show him through your actions that you have enough self respect to go out and find a man serious about you and not settle for second best. He might beg but stand your ground. He needs to win you back.

I think they're doing the bone dance when they're there together. Since dogs like bones maybe that's why they mentioned it.
