I have been in a relationship with my boyfriend since February 2015 now and it started off from a rocky start. From the beginning, I saw controlling features in him and about 3 months in I saw his temper. In my friendship group (which is all very close) is someone I used to like and slept with a couple of times; there was nothing between us except friendship when I got with my boyfriend, and we remained friends. Sometimes my friend would text me asking for help with studying whilst we were at school- we would literally sit in a teachers room with teachers around, whilst I helped him. I also was one of the only people that knew about his depression/suicidal thoughts. My boyfriend realised that we used to be how we were, and said I had lied to him and that I was texting him behind his back, which I hadn't, I would have happily told if he asked. Due to this reaction, I have since lied to him about texting my guy friends because I have been scared of what will happen, saying it hasn't happened and he has found out through looking through my phone. Recently, (twice) he has looked through my archived imessages on my laptop and my facebook messages, where he found in the second month of our relationship, me saying to my friend that 1. I preferred taller guys, 2. I looked at one of my exes facebook pages, 3. I found it strange to see my ex kissing someone in front of me, 4. I found someone really attractive when I was on holiday (this was also at a time we were REALLY rocky, as I was away and it made him angry (?)). I have spoken to my friends about this, and how he has been controlling me and my mental health has plummeted, alongside a family member who believes that I have done very little actually wrong. I would never cheat on him, I just don't want to completely sever my friendships (he thinks you cannot be friends with a guy). Recently, he punched through my favourite wall print and smashed two of ornaments, all on separate occasions, because of something he didn't like, such as me not telling him I was smoking at a party. The problem is, he understands me on a very deep level and we have had some amazing times, travelling and laughing together; we even have a trip away booked for his birthday next week. But now he feels so hurt by me, what can I do?
