What do I do about him?

I have been best friends with this guy since freshmen year of college. We're juniors now. Well we used to tell each other everything but then towards the end of sophomore year, he confessed his feelings for me. At the exact same time, my dad dropped a bombshell on my family about his affair with another woman and how he was moving out. This was a shock to my family and it destroyed part of me. Upon hearing this news, I sort of threw myself into a weird relationship with my guy friend. I really liked him but I didn't know how to deal with my feelings and my dad leaving. So this guy and I went on a couple dates where we kinda just cuddled and watched movies. He would text me everyday, however I never would text him first. I never even fully told him how I felt about him. He told me but I told him we would see where it would go. I couldn't handle having him as a boyfriend and then my dad. It was too much. Well this year, sometimes I'm positive he still likes me but other times I feel like he flirts with all the girls. In October he had asked me to go to this Halloween parade with him and he said that he missed talking to me, however I didn't follow up on him. He sometimes will message me but not nearly as much as he used to. We don't talk anymore because of the reality of us sort of "dating". I miss him so much it hurts. I dream about him every night (weird I know) and I can't get him off my mind. I never did tell him about my dad so he has no idea thats why I broke things off. What do I do?
