Is he really genuine, does he actually still love me?

Basically in 2007 a boy joined my year at school and since then we've been out and it lasted for about 2 years, then about 6 months ago me and him split up, and didn't talk, and he moved back to where he orignally came from, but he still used to mention my name to others, now he's back and he told me he still loved me, and we really did love eachother before, we both lost our virginities to eachother, and i felt like i could be myself around him, and i had a really bad thing if a boy put his hand round me, i'd flinch, but with him i didn't, and after he's came back, i've meet up with him, and we've been getting and that, but we ain't together, but he keeps mentioning , and i know i would, cos i have before but i'm scared its all he wants me for, and when i ask him if he actually does like me, he'll be like, jess, i love you, i wanna spend the rest of my life with you, i wanna marry you, and have your kids, i can't wait til we get our own place together, which is what he used to say before, but theres something about it i don't thinks genuine?.. he keeps saying. i think we should and that about , and i've said, i dont wanna be used, cos i'm a open minded person, and he'll be like whos getting used. :/ what you think?
