Week Vacay To See My Ex ADVICE NEEDED😬🙈

Hello ladies! I need some serious help lol. I'm 21, and I broke up with my bf of 2 years in October of last year. We went to high school together & started dating senior year, he's in the military and I'm in college so we had a long distance relationship most of our relationship. He said the reason was that he needed companionship and that he thought we should part ways. We stopped talking but started communicating more frequently this year mainly through Snapchat. We've started flirting more and had a bit of sexting going on. I mentioned going out to visit him in order to possibly take a step in building our relationship back, and he seemed for it but said he wanted to go slow. I'm on edge constantly bc I still love him and want our relationship back, better and improved, but I'm worried I'm coming on too strong and he just wants to use me to fulfill the physical connection he's no longer receiving and I'm easy bait lol. He's never lied to me but I don't want to set myself up to be hurt again...should I withhold sex with him on my week trip to see him, even though I want to?
