Someone from my past?

I DATED someone a few yrs bck that hurt me & as time past we've b really gd friends. He's now saying tht he thinks & alwys thought I was a great woman & texting, callng, & askng me out a lot. He's jokingly said thngs like he's chnged a lot frm the time we 1st met & how he's waitting 4 me 2 b ready 4 marriage in order 2 get married. It's scary bcuz I've healed & learned frm what I went through w/him. I care about him & thought my feelings were gone until he told me tht he's nvr stopped loving me & will always love me. What's a 28-y/o girl 2 do...He's 36 y/o.......How do I knw if he's not hust missing what he once had w/me?
