Help!!!!

I met this guy (who is now my ex boyfriend) on Tinder. We dated for 4 months until I moved away. We were both of each other's first (virginity wise) and I was his first girlfriend, 2nd girl for him to kiss, and he had only gotten a HJ from one other girl. He is and probably always will be perfect to me in my eyes. I moved away in December and we did the long distant thing for a little over a month, but then we decided to end it because the 2,500 miles between us was to much, since we were both college students. I still talk to him everyday almost, and snapchat him all the time. I'm still in love with him and he is the person I wanna marry and make babies with. 

So the question is, how do I know if there is still a connection between us or is it just a friendship? I'm flying back home at the beginning be of May to see him and my friends, and he says that he thinks there is still feelings (mutually). But how do I know that it's love not lust? How do I know it's my heart not my pants doing the controlling?
