So DP of 2 years went out last night for a Christmas party. For various reasons I ended up staying up til 3.30 when he got home. I thought hed be pleased I'd waited but instead we had a huge row about how I apparently dont trust him and that's the reason i waited for him to come home. Apparently I was expecting lipstick on his face, or perfume on him from him shagging another woman. This is mental and never even crossed my mind. He walked out cos he was disgusted at my lack of trust, then came back an hour or so later and said hes going to bed, but I need to know its over. I'm literally reeling and I've got no idea what's happened or what to do now. I love him so much, I dont want him to leave but i cant see a way to stop this happening. My heart is actually breaking
