I met my partner on Facebook I was friends with his cousin and made a comment on a post. My partner then decided to reply to me to make fun of a word I spelled wrong. I reached out to him to ask if he was mad at me (severe anxiety issues as a teen) and when he said no we couldn't stop talking. We never ended up meeting in person for almost 5 years despite living in the same city.
One time I got super drunk and couldn't take care of myself so I called him up to see if he'd come over because I had no other friends at the time and he never left my side. Literally, he came over just for the night and he kept asking to stay another night and eventually asked to move in. It's been 3 and a half years now
