In Law Problems...

Has anyone had issues with their S/O’s patents? I live with my girlfriend and her parents and just recently, my girlfriends mom and I got into it over something that’s a long story. It’s honestly hurting me so much that we’re not on the same page right now, because we’ve never had problems before. I love my girlfriends mom and she’s done a lot for me. So this whole disagreement is hurting me and my girlfriend feels stuck in the middle, which I 100% understand. I just feel so alone in this, I feel scared that what if this makes or breaks my relationship, and since I live with them I definitely don’t feel wanted in the house right now. So I’ve been spending the day at my moms. Does anyone relate? Or have any words to help me feel better? Because I feel like complete shit, and could really use a friend right now..
