is hard for me and maintaining friendships even harder. Why? Is this how everybody feels?

I don’t have an extended and close family... just hubby. I try to make friends I guess to make up for that empty part of my life.

I have formed social groups... invited people to get together... I include new friends in other groups I’ve found... I find that people don’t reciprocate and invite me to things. I just don’t form lasting friendships.

What am I missing?? Do I perhaps try too hard? I’ve wondered if I am not a good friend to others... maybe I’m self absorbed and I don’t realize it?... but I’ve also wondered if I just befriend the wrong people and then I feel taken advantage of. I used to easily like and trust people but I lately I don’t trust easily at all. I often feel sad about this.
