Sex life, depression, worried
I'm 20 and with my boyfriend since I was 19(I'll be 21 in march) he was my first boyfriend and I was his first serious girlfriend(he's 28). At the beginning it was all just fun and games and after 6 months he broke up with me because he didn't want a realationship, but after two weeks of continuos contact(mostly his part) we got back together and things have been amazing.
But for the last 6 months or so, our sex life has been dwindling. We can go through periods of just once every two weeks which I find difficult as I only see him on the weekends. I noticed that when I tried to initiate sex I.e kissing, touching he would simply give me a peck and pull me in for a hug. I used to ask if we could have sex that evening(he lives at home with his mom and brother so we can't be spontaneous) and he would assure me we would have a good time, and every occasaion he would make (what seemed to be to me) exscuses, say watch dvds until the early hours and then say it was late so we best go to sleep or go on the internet and look up sights. There were many nights I would cry myself to sleep and eventually it was too much and I wrote down what I wanted to say, if said it face to face he wouldn't understand as I would be non-stop crying). He apologised and said he didn't no what it was and re-assured me it wasn't me it was just he was never in the mood. Things were OK for awhile and gor better but we'r now back to where we were but slightly worse. During the entire Christmas period( I had holidays so I spent the majority of my time with him) we wouldn't have sex unless we'd be drinking, otherwise he was to tired,wasn't in the mood etc. We don't even do anything else sexual anymore,he gets horny and I will do other things other than sex(I know that's not the only way to be intimate and sometimes its easier when your caught for time) but he'l turn me down and just say no. I'm beginning to seriously think it's something about me, although he tells me it isn't but it's hard to believe when he says no top me. He says he thinks he might be depressed, which I can see coming through now and I'm scared it is because although his sex drive is almost nil, his need for affection has gone shooting up. He always wants/needs a hug and he was never that type of guy(he's very macho,so much so he doesn't believe that guys say "i love you", I don't know where he got that notion but I've known him so long that's not an issue). He's getting very paranoid lately too and snaps at things I say that are clearly a joke and he takes it all to heart. I started a college cours back in october(it's only for 6 months and we'r both otherwise unemployed), and I think that's bothering him because he thinks that I think I'm better than him some how, even though I would never think that. I don't know what to do, he seems scared and lately he looks like he's got a lot on his mind but he's a man so he won't tell me.
Any advice on the sex or depression thing would be much appreciated :)
