Long Distance Lust or True Interest

A guy and I met ver randomly and "dated" very casually for about 2 months. We would meet in a half way point for us both since he was in AL and I in FL. We ended things after a little over 2 months of talking everyday and being getting very close, emotionally and physically. I grew feelings deeper than he and we ended things. When things ended it was confusing and on a decently bad note. 4 months later he has all of a sudden shown up again and said "I was reflecting on people that fit well into your lifestyle and I felt we meshed well". He says he missed me and it's not just physical. How do I handle this safely and I want honest opinions, ladies.
