Hi, I feel quite silly even posting this but not sure what to do.
I've felt for a little while that there has been some distance between me and dp, I don't really know how to explain it or if I am being irrational. I am suffering quite badly from depression at the moment so that might be clouding this iyswim. I feel very isolated, and like we've grown apart, its as if the thing that interest me don't interest him and vise versa. I think its differences that have always been there but have become more pronounced recently.
We basically got together very young and have been together almost 10 years now, + one primary school age (being vague so I'm not recognized here) dc. DC wasn't planned, we discussed abortion, I couldn't go through with it. We both adore dc but I think I've found parenthood a bit more enjoyable than dp at times, not sure I'm being totally fair here as I have struggled too at times, I just feel like I've had to throw myself into it a bit more. Maybe motherhood has changed me more than dp is what I'm getting at.
Dp is still super supportive and caring. But I can't help feeling the distance. Sex is a bit dysfunctional to be honest. I've lost all my confidence post pregnancy. I'm embarrassed and inhibited. I sometimes feel angry during sex as well. Not sure why.
Dp has started going out more with work recently, which I'm glad about. I've always been one for going out and letting of steam and think we both need too from time to time. Its just there's woman at work he seems quite close too.He's even said she reminds him of me. and she looks like me pre annorexia, pregnancy, depression which have ravaged my looks a bit, and made me older. Someone I know had them back to theirs after a drinking session the other day and I think mistook them for a couple, though dp thinks he was referring to someone else they were with. There's also a photo of them messing about on fb, nothing incriminating just reminds me of when we were first together and we used to mess about and have together,making eachother laugh. and that never happens anymore 
I really feel that the sparks gone, and seeing them makes me sad because I remember how much in love with him I was when we first met. I think I'm projecting big time, its not necessarily his relationship with this person that is the problem, but our relationship.
Two years ago I had a EA, it didn't get physical in any way and was nipped in the bud but the feelings were there and it was way out of line. It hurt dp (I would imagine,although he didn't express much emotion over it) and we discussed breaking up but he didn't want to. I'm glad we stayed together, especially for my dc,, but I hope that's not all that's holding us together
I don't know what I'm looking for, sorry this is long and rambly. Is there a chance for us? or is it going to carry on being joyless, and both of us looking over our shoulders getting our heads turned by other people? is my depression clouding this or are there problems? Any advice much appreciated.
