You are quite selfish and strangely entitled, OP. I wonder how long it’ll take your bf to realise it and grow tired of it.
It’s not entirely clear what you bring to this relationship.
The fact that his exW didn’t work is irrelevant, really. I presume it was a long marriage and she was raising the kids, kept the house and supported his career. He, in turn, supported her.
Now - you enter the scene and think it’s totally OK to live there rent/bills free, and also judge his lifestyle, count his money and criticise his friends/weekend activities.. And yes, he is also supposed to entertain you on weekends because you are bored.
I feel bad for the guy as he could do so much better.
If you aren’t seeing this all - just think about what’s happen if you broke up. Your nice free lifestyle would change dramatically. And you’ll have to get out and get a job. Any job. This is your alternative if this relationship ends. So - give yourself a shake. You are massively lucky.
So - if I were you - I’d start feeling at least grateful and stopped giving him grief over his rather understandable desire to spend time with his friends/acquaintances.
And also - get a job. Events management isn’t coming back any time soon. So you need to figure out your next move as the excuse that you had a hard year isn’t gonna fly to much longer. Everybody had had a hard year.
