I have been noticing something odd about my roommates relationship with her girlfriend. First I see each one sleep on the couch from time to time. Second I hear about how my roommate is making out with other girls. Then her girlfriend has shown some fleeting interest in me then, her girlfriend keeps commenting about how she wants to see a real life man package again (in front of me no less) and, finally they keep saying how they will stay together forever over and over (to me an indicator of denial about how bad the relationship really is).

It may be nothing but is there something I should do to keep as safe as possible in case it goes nova?

I broke up with him and now guys are hitting on him and he’s not avoiding it , not flirting back but he’s not telling them to back off.
