My transition to poly has been rough

You didn’t want to talk to her because she was straight?

Look, your social skills sound remarkably poor as is your attitude towards other people. In this thread, you say

You have 254 posts and have started 80 threads. Seems like you often post several times in your own threads, so have much have you participated in threads that you didn’t start? Are you interested in anything other than your own narrow interests?

That does sound like you were trying to use her for your own purposes rather than genuinely trying to be friends with her. Did you actually like her or did you just think she would be a conduit to sex? Did you blow off the straight girl because she wasn’t sexually available? Maybe her friends noticed that.

Yeah, probably.
