Bf said He's Not Sure And Doesn't Know If We Should Stay Together

Hi, i'm kind of new to this. I've been in bad shape the past few days. I have been with my boyfriend for more than a year. Sort of long distance relationship (1.5 hours away). Both full time graduate students. i'm 31 and he's 30. We had a wonderful one year and even went for an anniversary vacation. We did have arguments along the way - mostly about his close relationship with his ex and her son, my paranoia of being cheated etc. We both have issues. I tend to be overdramatic and i expect him to be a mind reader. He tends to give me silent treatment for days when he's annoyed/unhappy. But i was hoping to work it out. I cook, clean, and organize his apartment. He's a messy guy and it irks me sometimes. We had an argument days ago - and I know it was my fault. I was being overdramatic. But i apologized immediately afterwards - several times. But he gave me silent treatment for 3 days - no reply nothing. Finally he did. I asked if he's still angry. He said "i'm not angry". I asked if we're ok. He said "i don't know'. I apologized again. Then he said "i feel like we're in different wavelengths". To me it sounds like a breakup. So I asked "are we breaking up?". He replies "I'm not sure". Since we're in LDR, it's difficult to solve such issues. I don't want FaceTime nor text. So we decided to meet face to face tomorrow. I don't know what to do anymore. Convince him not to break up? Propose a trial break up? or completely break up?
