My girlfriend talks to this girl a lot (who's also gay) and I'm paranoid she's going to cheat on me with her since she's so much prettier than I am and they seem to get along well. The girl made a comment on my girlfriend's post recently saying "My -GF name-". It made me super uneasy, honestly. I'm always paranoid my GF is cheating on me behind my back. She's reassured me a lot that she wants only me but I don't know for sure. She also heart reacts this girl's pictures on Facebook a lot and calls her "beautiful ❤" Ugh. I hate this.
