Hey again, OP.
Based on how this thread has been going, I feel more confident in suggesting you get into anime.
There are some people who won't ever be in a relationship, and some who probably shouldn't ever be in a relationship. You might be one of those people, but it's not a bad thing! 2D may not (yet) entirely fill the gap left by an absence of human companionship and warmth, but it's certainly better than nothing, and better than the repeated bad experiences you seem to be putting yourself through.
Anime and manga are the good shepherds, always happy to lead lost lambs into the fold.
