I finally managed to reach out to my old best friend and going to leave my girlfriend alone for a weekend
Is there anything bad happening between you and your girlfriend? Couldn't you just take your girlfriend with you to meet the friend?
Not really. Just that she is jealous of my female friend and always says that I spend too much time with her.
Your gf's feelings are understandable too. It's cool that you're in touch with your old friends. I hope you'd have fun spending time with her.
Nah, I'm going to tell her that we should chill and hook up.
Oh, that's not a smart thing to do. Shouldn't you at least break up with your girlfriends first before making that attempt on your friend? Otherwise, that is called cheating and you will be labelled as a cheater, and people hate cheaters.
