Ex popped up at my house! Confused

I broke up with my ex last October because I have trust issues. When me and him first started dating he just completely disappeared. It was in the process of us getting to know each other. Every thing was going good and the next morning I woke up he blocked me on social media and ignored my calls and texts. I was hurt. A year later I ran back into him and he was like he been thinking about me and he wanted to talk and explain himself. So I gave him a chance. Then one day I didn't hear from him at all. He wasn't responding or answering my calls. So I flipped out and we ended things. That was months ago. We had completely stopped talking. Late last night he came to my house. 230am! I was sleep. I looked out the peep whole and I was in shock. I let him in. He was like he missed me. He just got off work and he came a few times in the afternoon but no one was home. I feel he must really do miss me but at the same time I'm talking to someone else. It's long distance and he is the man of my dreams. But it's still new. My ex was a good guy I just didn't like how he disappeared. He said he was going through a lot. I'm just confused. Both are good guys. The new long distance guy is in my hometown and I'm trying to decide if I want to move back for my own personal reasons.
