We've been together for one year and 6 months.

He cut it off 2 months in.

I don't know what to do. We live together and I have nowhere to go in this state

Its his place, but his father also lives here and has taken a liking towards me. (not in a creepy way or anything.)

Overall he's really good to me. He's sweet, compassionate, and is always bending over backwards trying to help me through my depression, but... that still happened. I confronted him and he admitted to it and apologized, saying that once he realized he wanted to be with me he cut everything off....which he did, but I still feel a little betrayed, yknow?

We are both 21. his parents are going through a pretty nasty divorce, so he agreed to stay with his father to help with bills so he could afford a divorce attorney :/

I myself am not independent enough, either. I work and pay my bills, but after getting kicked out, he and his father agreed to let me stay with them.

It sounds like you're in a very difficult spot. What made you confront him now after all this time? It's really important regardless of when it happened to talk about why it did and talk about regaining trust now that you know about everything.

he's been very distant, and after talking with a friend she implied that maybe there was something going on, or someone else in the picture I didn't know about. I normally wouldn't have gone through his phone-- I know it was wrong, but I did and I found the messages dating back to about four months after we got together. At this point he had already met my parents and everything. :/

I can relate. My boyfriend and I were "talking" for months before it was official. I later found out while we were talking he was sending....suggestive messages to another woman and did some things with another. I am torn because we weren't technically together I guess, but at the same time we weren't nothing. He has since blocked these woman, but I am always worried when we aren't together. I am mostly over it, but the forgiveness is hard. Knowing he was doing stuff with some other woman and then probably kissed me that same day makes me sick to my stomach even after all this time. I have had to seriously debate if I want to continue. I love him, but the trust hasn't mended yet.

You're in a difficult position and I'm sorry this happened to you. I know you're living with him and there's a pandemic going on so moving out may not be feasible at this time. I will say that I also dated a guy who did some skeevy things after we had been dating a while but I gave him the benefit of the doubt. He ended up doing it again and Iooking back I wish I had broken up with him when I first found out. At the time, breaking up with him was very difficult because it felt like I was "throwing away" 2 years of my life. That feeling passed quickly. You never get over someone cheating on you; it will always be in the back of your mind. It's almost impossible to get over that breach of trust. My only regret about that time is not breaking up sooner. Again, I know you're in a tough position but if you can at all, you should consider breaking up and moving out.

edit: rip didn't see that this was two years ago D: Hope you're doing better!
