If it makes you feel better I am like that too. I went a few months without talking to one set of friends and the eventually just washed their hands of me. I am like you and just really bad at keeping up with contact with people.
My sister and I were talking and since my latest travel plans have been cancelled. She told me that I need a sugar daddy. So I confess that I need a travel sugar daddy. Someone who will pay for all my travel indulgences! Too bad that isn't a real thing lol
