We’ve been together a month n a half now, just two weeks ago though I found out she has a male roommate in her apartment, i almost snapped on her but checked myself since this relationship is new. My girl told me not to worry since he has a girlfriend who he’s getting ready to propose to anyway so cheating is not the issue. The problem is that yesterday when she came home from work he was in the living room bucket naked on the couch (which is hers) masturbating to porn on the tv, he didn’t try to cover up or anything he just looked at her said hi and went back to doing it. She said she’s ok with it as its half his apartment to but I feel like I need to step to him and lay some ground rules, im not cool with him walking around naked either its just disrespectful. I trust my girl and she told me he’s not her type so im good on that part, I just need to check homeboy, planning to do it tomorrow, might bring a blade just in case…I should step to him right?
