Well that’s gay of her to do, no pun intended.
P80 is the most authoritarian, put your foot down and establish the law stuff in the cabinet. When you wear P80 people tend to get your message in a very direct way. Doesn’t take too much either. 
Your gf left you because of a gay roommate?
Dude I’m sorry but it sounds like you need cut the victim crap. Take some initiative. Do something about this situation that seems to be damaging your life so profoundly.
Maybe your roommate is into you because you’re a sensitive beta guy. I have many gay friends. They don’t hit on me though because they know that I mean what I say. That when I say “stop, don’t do that”, I f’ing mean it.
Perhaps you should make yourself more clear.
No offense..
I agree with future. Either that or kick him out/get a new roommate or just put your foot down for the final time.
Leaving you because your roommate is too gay is a shitty excuse. She left you for another reason and used that as an excuse. I’d put money on that.
If, on the remote chance that was the real reason, seems to me you’re better off without her. It’s a dumbass reason to leave someone.
Dress like a slob, gain a ton of weight, and shit your pants frequently. problem solved.
Your GF is not going to leave you because your roommate is to gay unless she has some reason to think your gay as well. I think its a excuse,
Tell me what pheromones you frequantly wear ?
