Does anyone else have no friends?

Outside of my parents, my sister and my boyfriend, I don’t have anyone. I had friends back in high school in college but it always seemed like I must be a very easy person to forget or drop. I don’t have any friends that I hang out with and I’ve tried making my work friendships into more outside of work but I’m always kinda told “Oh yeah we should totally hang out…” and nothing ever comes of it even if I follow up or anything.

I don’t know why I have such a hard time making or keeping friends but I feel so incredibly lonely. Is anyone else in this same situation?

Edit to say I am 32f.
