Sorry to hear you're in this situation, OP. I was in a very similar myself. Bf was unemployed for almost a year and would stay at home all day so I NEVER had any time to myself (our flat is very small so we were always in the same room when I was home from work). I know him not having a job was depressing for him and that's probably when he never felt like going out even though he has a good amount of friends.
When he did eventually tell me he was going out for the evening, I'd feel guilty for being so happy, but I had forgotten what it was like to be by myself (one time I realised it had been 6 weeks that I had been in the flat alone).
I guess the only difference is that he was fine with me meeting my mates and would never accuse me of cheating when I met them. He was a bit bummed sometimes when I went to meet them without inviting him, but I just wanted some time apart.
We actually ended up breaking up (about 3 weeks ago), but there were other things wrong with the relationship, not just this.
It's quite ironic as now he's managed to get a job, haha! Friends are saying maybe the break up gave him the kick up the ar*e he needed. Not that I'm saying you should break up, but I would worry about him accusing you of cheating when you want to go out without him - it sounds a bit controlling :/
