Boyfriend has issues with my shyness 😔

I feel like I have social anxiety although I am yet to build up the courage to see a doctor so maybe I am just really really shy. I find it close to impossible to talk to people. Over the years I have gotten a little better at responding if people ask me things but I still struggle to ask things back or go in depth with answers.

I've been with my boyfriend 5 years and we live together. At the start of the relationship we had some fairly big arguments about it but got past them.

But this weekend we visited his family, I haven't in over a year. He spent the whole weekend sort of resenting me and complaining that I can't talk to his family. I tried really hard to but I get stuck in my head and afraid to say anything. I feel awful that I can't be this bubbly friendly girl that his family can love but I just can't. I can't be bubbly with anyone but him and my parents. Not even friends.

He just doesn't understand but I am worried this will cause the end of us one day.

I hate myself for it I always have but I haven't felt that bad inso long. I forgot what it was really like. And how bad I actually am. And him being upset with me and I could see his mind reevaluating whether I'm worth it.

Trouble is I never meet new people so never get a chance to work on myself.
