If, right now, you have more bad things to say than good, I would recommend you having some time apart. This will breed anger and the world of 'what ifs' will just keep getting bigger. You will resent the time you've spent together, you already say you regret moving in with him. From what you've said it appears that you are both living with his parents at the moment. If you are financially able to, move out, with friends, alone, with random housemates, whatever. Give yourself that breathing space. Go to bed alone, text him when you miss him, go about your day without having to tell someone where you are. I moved in with my boyfriend at 17 (Jan 2008), while his parents were away. I moved to the next town, an hour away from my dad and was about 5 hours drive from my mum and sister (with no car or licence). 12 months later we moved to the city (5 hours) into an apartment his parents owned. We went to the same university, we had a lot of the same classes and a lot of the same interests. By the middle of 2011 we were having massive problems which were mostly revolved around my depression. We toyed with the idea of breaking up, we said we'd keep it together for my 21st, and just after that I walked out. He had no idea it was coming and was planning to propose to me on holiday that year. Next came the months of being half together, him trying to win me back, me experiencing a thrilling freedom while he was thrown into despair. I had great people to live with, good jobs, and boys bloody everywhere. He wanted so hard to change and we did get together for a while in 2012 but it just wasn't the same. He wanted to get married, he wanted kids, he wanted to travel the world with me. He even proposed at one point using a ring I already had. Things were hard, they were bitter, cruel, beautiful, sad, incredible and just plain heart-breaking. But I always knew it wouldn't last, he wasn't what I needed at that time in my life and I couldn't see him fulfilling that role later. He wanted kids? I don't. He wanted to work 9-5 for good money? He was supported by me the whole time and only got a job last year when I wrote his damn resume for him haha Thing is, when things started falling apart, I really do believe we both knew that was it. We were the couple that everyone called bullshit when the break-up become fb official. This is also why I hate Facebook. We tried, and we learned so much about ourselves and each other. We are still good friends now, even though he chews my ear off about absolute rubbish half the time and I smile and nod. I was there when he was working out how to get his girlfriend to become his girlfriend. I felt like I was in a rut. I didn't feel like me, I felt like us and at first that was incredible, but then it became suffocating. If the two of you are meant to be together, you will survive a break. Maybe start with a physical break, move out, start going on dates together ago, do fun things. You can then lead into a relationship break, where the two of you are completely independent for a while. You probably will have setbacks, the relationship you have entwines the two of you, it is really hard to start to think about what I want instead of what we want. You care about him, I'm sure, but you are important. If he is aware of how you're feeling I'm sure he feels inadequate, hurt, torn and probably quite similarly to how you do. You have absolutely nothing to lose at the moment by voicing your concerns. Except maybe make sure you've got a place to go first. If he is serious about your relationship, he won't be totally surprised. He will be hurting and you will probably hear some truths you really needed to. All you have from this is to learn. If you learn that you want to be with him and that your relationship can change for the better, then that's great. You may break up on amicable terms and keep in touch until down the line, 5, 10 years or whatever. But for as long as your harbour these thoughts about him, the split between the two of you is going to get bigger and more poisonous, which is something you won't ever be able to fix. A clean break is a break, but it heals so much better than a shattered limb.
