It can be platonic, familial, romantic, anything.
I’ll start: I recently moved in with my boyfriend, who lives with his wife and their son. They were already separated when we met, but his wife doesn’t want to divorce or move out, and she wants their son to live with both of them. My boyfriend agreed to those terms.
So now I’ve found myself in a pretty unusual situation…
Dated a trans guy for several years, thought I would marry him. Paid for his top surgery. Got it done at the same time I got my bottom surgery. We broke up a year later. Don’t pay for someone’s medical treatment unless you’re married to them. :/
