What do I do?! 😩

Hey ladies! I have a problem

I’ve known a guy since middle school and we’ve always liked each other

We went to different high schools but I still found him on social media. One day I went to his house and we did things. But that was 2 years ago. And ever since then it’s been on and off. I like him so much but I feel like he only wants me when he wants me. But I can’t help myself 😩

I haven’t talked to him in a month since we had sex. And now he just messaged me 😩

If I answer i know he’s gonna want to see me and I do too! But then I know hes gonna stop talking to me and come back later in weeks. Am I being used? Help ):
