I still can't get over the fact that my boyfriend 'talked' to his ex-SO after I specifically asked him not to. This might seem controlling, I know, but I really have a huge insecurity when it comes to this due to my previous boyfriend's actions in the past (he cheated on me with his ex). I told him to give me some more time to deal with this as I feel that I can really get through with this insecurity but he just needs to help me out with it for a little, you know? I just need to be able to trust him.

Twice, he lied to me about this.

1. I asked him if he's friends with this girl on Facebook. He said no. But they are friends.
2. I asked him if they talked recently. He said no. But they did. (saw the conversation after a fight)

I just feel so betrayed. I feel like I can't trust him anymore completely. I also want some legitimate answer as to why he lied to me basing from these factors:

1. I specifically asked not to do it to the point of begging because I am pretty sure that this shit will hurt me; and,
2. This girl treated him poorly. Had sex with another person while they are dating, even kissed a girl in a bar just because she wants to, forced him to fight another guy who likes her because she thinks it was so cool that two dudes are fighting for her.

He said that he was just trying to be nice to her, or even polite, that's why he talked to her. He was just trying to show her that he doesn't feel bad at all at what happened between the two of them. But, what about how I would feel? Did he even think about that when I specifically said that that kind of shit will hurt me?

I can only come up with two possible answers as to why:

1. He really doesn't care about how I feel; and,
2. (the worst answer) He still wants to get with this girl after everything that has happened because she's physically there.

Am I being unreasonable with this? I am really trying so hard to get over with this shit but him saying that I should move on from this just because he already said sorry feels so wrong.
