Is it normal to still think about someone after months?

I'm 17 and had a boyfriend almost two months ago. We really didn't date that long but we had a strong connection. There was a 3 year age difference so it was hard to hang out considering the fact that my parents would definitely hate his age. He didn't drive and I don't have my license yet so we never really got to hang out, and he said it hurt him too much to not be able to see me and that he loved me and I truly feel like I love him STILL I just miss him so much... I have another boyfriend but I just don't feel the connection and might leave him... Should I try to talk to the ex about how much I miss him? He even said it was only until it would be easier to be with me but I'm afraid he moved on.
