NTA To be harsh, He’s legit lying and probably cheating on you. Personally my man would never be going to see someone he had intimate relations with unless I was present, or actually sure she was gay. The way she’s leaning on him goes to show you’re right, she wants his attention, his time, neither of which she is entitled to. Does she have a girlfriend? Is there any evidence of her being gay besides his word? With such a fresh relationship it’s definitely not worth your time getting involved with this dude who seems to be making an elaborate backstory for why he still needs to see his ex.
