Hello and welcome

I know how you feel very much
I have no friends either. I was in a relationship before and I thought I could communicate with my partner, I often felt that he wasn't really listening to me. So we broke up. (not to drop any hints)

Sometimes when i'm feeling ESPECIALLY lonely, I write to myself.
I write how my day was, who I hated what was so bad or why I think I feel bad. Then I read it over to myself and use the paper as a cage liner for my birds poop :P
Or just destroy the evidence.
Everytime I felt a little better, sometimes you are your best listener

Maybe its best that you go after a temporary pych just so you can vomit your feeling on the person.
Its often better to get face to face time with someone else. I hope you can talk to your husband about your feelings though, don't be afraid HE'S YOUR HUSBAND.

Else as a strange man on a train told me while I was reading James Baldwin...
