Confused

So I eventually moved on. I had to. Went on dates and dated two guys. When things were kinda over with me and the last guy I was dating, my ex texted me. It was a booty call and since I was single, I replied. We texted little back and forth. Then we ended up meeting up. We hadn't seen each other in like 8 months. I went to his place, then he took me to this bar like a block away and we sat there for 3-4 hours, just talking. He told me then that he's deploying in February. He also kissed me. The night ended up with his having sex. (We didn't have sex when we were seeing each other) sex was amazing. 

So, to fast forward. We've been hanging out now a couple of times. And he's been saying stuff. He got really shocked when I said that I'm going home now in October, cause I was supposed to go home in November. Then he said that he should come visit me in Europe when he's back from his deployment. He asked a lot about the last guy I was dating. Recently he asked me if I've been on any dates and when I said I hadn't, he said he hasn't either and he asked me if he could go trough my tinder so he could see what guys were writing cause "guys are pathetic and it's fun". And I saw him, like he literally read every message and looked trough their profile (I don't use it anymore and I told him that). He added me on fb. 

So now, I'm leaving in two days.. and he said that if I want to, we could hang out and he could drive me to the airport. To me, everything that he has been doing and saying, to me that isn't hook up behavior. This isn't a guy that bullshits. I love this guy. I moved on but the feelings were always there. But what do I do ladies? I'm thinking about telling him how I feel. I'm not saying let's be in a relationship. But, I want to keep in touch while he's deployed and then when he comes back, take it from there.
