My ex [20 M] wants me [21/F] to visit him for ten days.

Long story short: my ex, let's call him Jay, and I were long term high school sweethearts. We both went to different universities and I broke it off because there was a lot of strain and distance between us. After 3 years, he messages me suddenly and asks me to fly to him in Virginia for the 4th of July. He's really pushing me to come, and even offering to pay for me.

My problem: I just got out of a 2 year relationship and it's been rough on me. I'm not interested in pursuing another relationship for awhile, and I feel like he's just trying to convince me to come back to him. I don't want to break his heart or get him excited about something that may not happen, and I don't want to use him either.

I would absolutely LOVE to go to see all the amazing sites and opportunities in Virginia, but not at his expense.

tl;dr: ex wants me to visit him for ten days to /maybe/ rekindle relationship. Not sure if I should because I just got out of a ltr.
