I have no idea how to have a non-sexual relationship/friendship

Recently I had another relationship fall apart and it's made me realize (again) that I do not know how to have a normal healthy relationship with someone. There always has to be sex involved. And for me, I don't know if I can even have a healthy sexual relationship right now. At this point I'm wondering if I'm actually ace-spec or if it's just the trauma, or an ace-spec alter.

I don't know. I'm tired and should go to sleep soon. But I wanted to get this out of my head while I was still feeling brave enough. I'm going to start seeing a new therapist soon. Feeling cautiously optimistic, but also nervous, because I struggle to say any of this stuff out loud. The words won't come out of my mouth.
