If somebody won’t be with you because of your identity, then they really aren’t worth your time.
“He won’t like me since I’m trans.” Then don’t like him back.
“She’ll break up with me if she knows I’m bi.” Then break up with her first.
“They wont date me because I’m ace.” Then don’t date them.
There are plenty of people out there, both allies and LGBT+ folks, who will begin and keep relationships with ace/aro peeps, nb/trans peeps, and bi/pan peeps. Don’t waste your time on those who won’t. You are worth a relationship with somebody who is not just tolerant of your identity, but celebrates it with you.
