Dreaded Facebook and exes.

I've been dating my boyfriend about 8 months now. In MY past, I have been cheated on, dealt with the divorce of my parents because of my father cheating so I have trust issues. My current boyfriend dated someone I went to high school with,I think probably a little over a year or maybe 2 years ago. We are all mutual Facebook friends so I see any interaction they have. The problem I am having is I cannot stand it that he will "Like" her pictures on Facebook or like a status update she's made. It makes me feel like he still has feelings for her. His stance on it is that they were friends BEFORE they dated (about 9 years, I guess) and only dated 2-3 months. From what I understand (bc this has been an issue) is that she broke up with him because she was looking for more of a father for her son and he wasn't 'ready' and that's why they broke up.
I brought it up to him a little over a month ago that it bothers me that he will like a picture of hers on facebook (the ones he likes are her with her son or just her son alone. I know that I'm sure he bonded with her child and I understand that.) I brought it up to him and let him know how much it bothered me and he hasn't done it since except for today when he liked one of her status updates. I immediately just began shaking and was so upset because I feel like he completely disregarded my feelings on the matter. We got into a big fight and he said I only asked him not to like her pictures and he can understand that but that just liking a status update is different. (This is ridiculous, I know.) He told me that he isn't going to stop being friends with her and that is what I'm asking him to do by not "liking"/commenting on her things. I never outright told him to stop being friends with her it just bugs me that he comments on her things. I asked him if he would like it if the situation was reversed and he said no but he also said he wouldn't tell me to stop being friends with someone. He told me that he will not stop being friends with her.

I know that I am carrying past issues with me into this relationship and I've tried to work passed them but I just feel like I'm not being completely irrational with this. I am worried that my gut is telling me something that I am trying to ignore or maybe I am just being irrational. He keeps telling me that I take Facebook way too seriously.

Another side note is that I was being a little nosey a few months ago and looked into his bedside table, it has a cabinet with a drawer on top. Inside of the cabinet he still has pictures of him and this Facebook girl and also pictures of him and some girl I'm assuming he dated at one point. Is that something to be worried about too? Obviously I am not going to bring that up because I was in the wrong for snooping.

Other than this we never fight, we have a great time together and he really is my best friend. This is killing my thoughts and making me depressed and anxious.
I've talked to a few of my friends about this and they tell me I am not being irrational but I just thought it might help to get a completely separate parties opinion.

Thanks for any advice anybody can send my way.

Hey,

You didn't mention ages here, but I'm going to assume that you are all around 30?? Whatever the case, you all seem to be of an age that brings a lot of history with it. I am 28 and just about single, but I'm finding that the women I meet have a lot of history behind them (as do I). I think it's important to recognise that, firstly. Leading on from that, however, is the fact that some of us can be sentimental. I'm saying this in relation to the pictures that you found in his bedside locker/drawer. You know, I've kept stuff from ex girlfriends too, purely because I'm a sentimental guy. I have pictures on my computer too that I would never delete. have you kept anything from your past??

Also, Facebook is a 'playground' really and it's not a true reflection on reality. I can understand the upset that you're feeling, but Facebook will never do much with regard to changing the course of time. Also involved in this is the child, and I'm sure (as you've mentioned) that he bonded with the child a lot. That's something that might never change, and perhaps it's easier for him to be on speaking terms with her (the mother) than to be bickering/arguing.

If he has made it clear that you are the one he wants to be with, then I think that you have to remember that each time that you feel uneasy about something that happens on Facebook. However, if you feel 'unloved' by him in any way, then it could be contributing to the problem. I mean, do you feel that he gives you enough attention?; would you prefer to spend more time with him?
