Need Help Please

There is this guy that I used to talk to when I was younger. I fell for him hard. My parents went off on me and him when they found out about it. He is now 26 and I’m 18. Over the years he’s got engaged and things didn’t work out with his relationship and neither did mine. I feel like feelings were lost a little until he started texting me again. My ex is snapping me and so is he. He’s talking about how he misses me and so is my ex. Idk what to do! Please help!
