@Headhurts you already suspect that he is talking to his ex-girlfriend, and you are pretty certain that he was looking at pictures of her, because you found his “recent activity” with the time and date showing that someone looked at pictures of his ex (and it wasn’t you, so it must have been him unless someone else sneaked into the house and looked). Then he told you that he did not look at them. This whole situation is a problem on many fronts.
Even when people “get on great” as you have suggested, you need to figure out what that really means. In my book, people that get on great communicate well, are not secretive and have no reasons to be jealous, because the other person doesn’t do things to instill jealousy. Just because he doesn’t hit you or yell at you, doesn’t mean you get on great.
For me, it would be a huge problem if my mate was super secretive and private all the time. I would only want to be with someone who wanted to share his thoughts and feelings and possessions with me. I would need to be in a relationship where there was pretty much equal give and take. That’s not to say that relationships are always 100% equal, people are different, but there has to be a pretty good balance. Your relationship with your boyfriend does not have balance.
If the relationship started out like this, why did you continue to stay with him for 6 years? I probably would have left a long time ago. Just because you two don’t fight or have arguments, doesn’t mean that there isn’t a problem within the relationship. If there is not good communication, there’s not a good relationship, IMO.
And speaking of lack of communication, you aren’t really being honest with him about your mental illness. He only has a limited view (the tip of the iceberg if you will) about your situation. You even admitted that you didn’t want to show him these threads, so you’re not exactly sharing everything with him either. Plus, it seems like you are not taking the proper steps to help yourself either.
Re-read what you and we have discussed on your Other Question There is plenty of information about how and where you can get help, but nothing will help if you don’t actually take the steps. Otherwise, you can keep on asking basically the same question over and over and over here on Fluther and continue to get the same kinds of answers.
We all know (by now) that part of your jealousy and insecurity towards your boyfriend is being fueled by your mental illness, but part of it is actually warranted, because he probably did lie to you (but I think he only lied to you so he wouldn’t hurt your feelings) and partly due to the fact that he is so secretive. This is a bad combination.
At this point, if I were in your situation, I would ask this guy to join me in couples counseling or break up with him, because this relationship has some major problems. Neither one of you sound like bad people, but there are clear problems (at least they seem clear to those of us on the outside looking in, and that’s based purely upon what you have told us) and those problems are not being attended to. If he didn’t want to go to couples counseling, I would probably break up with him, because he would be, in essence, telling me that our relationship wasn’t worth saving or fixing.
You keep talking about needing to change yourself, what you really need to do is change how you deal with situations, with your own mental illness, with how you react to his explanations, with how you figure out whether to stay with him or to go, with whether you take steps to solve the problems rather than just agonizing over them and basking in self-loathing.
All of this would be so much easier if you just showed him these threads. You would know instantly whether or not he was willing and able to work with you to either break up (because you might not be a good match) or work with you to get you some help and change the way he communicates (he doesn’t right now) with you. Or you, yourself can continue to be secretive by not showing him these threads and your situation will just circle around and around. Fluther is a great place to get some ideas and to get a kick start, but if you don’t actually take the steps, then nothing we can say or do will be of much use.
I wish you the best of luck.
