Do I stay or do I go?

[Guest]

My boyfriend and I have been together a while now, and at the beginning things were fantastic between us. He would call everyday, spend loads of time together and have lots of sex. recently he has been having some major problems at work and he has started to stress out about it all the time. I have been doing everything in my power to try to help him, to cheer him up. but all he seems to be doing is pushing me away. We went out last week with people from his work, we were all very drunk and he started arguing with the person he doesn't get on with at work, I have never seen him get so angry before and am not ashamed to say that it frightened me a bit. I tried to calm him down and he shouted at me to "shut the **** up!". He has never ever done that before and i said no more of it until the next day, I tried not to make an issue out of it but let him know that I didn't like seeing him that way. Since then I have been doing my best to cheer him up but with no avail. We had arranged to go out at the end of the week to celebrate me leaving my job and the night before he text me saying that he didn't think he would be good company and asked if we could leave it til another time. this is happening more often these days. I was bridesmaid for my cousins wedding, it was supposed to be the first time he was going to meet my family. He was working nightshift but said he would come for a couple of hours. the morning of the wedding he gave me a lift to my cousins and said he would see me later on. that night i text him asking what time he was coming over, to which he replied that he wasn't going to bother because he was skint! needless to say that I was upset as I had been really looking forward to him coming. I have always turned up to things he invites me to, his work night out, his birthday, his friends birthdays...etc the list goes on. but it seems that the things that I find important he lets me down. I know its because he is depressed about work, but I still find it very hard not to show my disappointment to him. I love him but really don't know how much more I can take. i have offered to back off and give him space but he says he doesn't want me to do that, yet his actions say the opposite.
