I dunno, sometimes solitude is preferable, but I will not discount your loneliness—not my intention to invalidate.
I had one boyfriend my senior year of high school, sort of on-and-off. He recently died of a meth overdose. I had a child with him before he turned to hard drugs. She just turned 19 last month.
I married someone else shortly after delivering said child, and was married for 8 years. It wasn't that great. More or less like a business relationship, with a bit of "I'm afraid for my safety" thrown in at random times. Had two more children, both teenagers now.
Been divorced for 11 years. Dated twice in that time, both extremely intense and confusion relationships. After getting the right treatment for PTSD, I discovered how much I enjoy my own time, so I guess I've accepted that I'll be alone, at least for the time being.
The past relationships I've had have been quite upsetting and exhausting. I don't think I want another one if it's anything like the previous ones. Then again, I've only just understood my neurodivergence, and getting different needs met will likely lead to a different kind of partnership, if it happens.
Still, I like it with just me and my kids. When they move out, who knows?
