Am I Crazy?

About 2 years ago the guy I was madly in love with, cheated. In our house we bought together, in our bed, that I paid for. We were the “perfect couple” in our hometown. Everyone thought we were going to get married. I even thought that. He was every girls fairytale dream and I thought I had finally found my one. There was never any signs of cheating. So it caught me off guard. We tried working it out, twice, but he just can not tel the truth. Since then I’ve dated a few guys. They turned out to be complete idiots. Well I’ve had a bestfriend that’s a guy, since high school. He’s always been my comfort. He’s always been the calm to my storm. When things go wrong, I can go to him. We’ve recently decided to take our friendship to the next level. He’s an amazing guy, so sweet and so good to me. I’m just scared I’m not feeling the same. Some days I do and some days my anxiety runs a muck and I feel like I shouldn’t be with him. I care for him and I would be completely devastated if he were with someone else. Am I making sense to you guys? Because I’m not even making sense to myself and I don’t want anyone to get hurt. Maybe we rushed it? Maybe we need to slow down. I don’t know. ANY advice would be helpful.
