help please!!

I'm 37 weeks pregnant and I'm in an amazing relationship with my boyfriend of 3 years and I'm having our second child here very soon. I am in need of some help, the guy who I "loved" in high school (I'm 24) dad just died on Christmas eve. Since then I cannot stop thinking about how he is and I have been having dreams about him. He was a horrible guy Very controlling and abusive so I definitely don't wanna be with him or anything but I don't know if it's hormones or because he was my "first love" 
Has anyone experienced this and can tell me what to do?! 
Edit: I wanna just say he has a fiancé and I don't want a relationship with him at all. I just wanna say something to him letting him know I was sorry and his father was a great man. He lost his dad grandma and grandpa and doesn't know his mom so he is all alone now. I guess what I was asking was if this is a normal feeling to always care but not like/love him.
