I’ve been in a relationship with this girl for about four years, and we started living together around eight months ago. Recently, I checked her phone and discovered she had been sleeping with someone she claimed was just her roommate and friend. Finding that out really changed how I felt — my feelings for her dropped significantly, especially since our families have already met and done introductions. At the same time, she went through my phone and found nude photos of several girls which I forgot to delete after we started living together. The reason I had those videos is because I’d rather masturbate than sleep around and risk infections or increase my body count with people I don’t see a future with. Right now, I feel emotionally detached from the relationship and I’m just staying until I find someone else.
