More than friends?

Background- In December 2017 I met this guy. We both worked for the same company abroad. He's from England. I'm from the US. I have been living there for 2 years. We started talking lightly, then in January we became FWBs real quick. we talked every day, etc. At the end of March He ended our FWB relationship and decided to just become friends. Our texting got lighter to each other and came in waves of him texting me. One week it would be every day. The next would be every couple days. We later had an unplanned hook up in late April. Thats was the last time we hooked up. We then texted every day but as friends. He left were we lived end of may. He then went traveling with his friend from home. I left in June to go traveling. we ended up traveling together for like 3 weeks. I met his friend from home, got a feeling he wasn't told we use to be FWBs, was constantly teased for flirting with each other and having sexual tension. Became really good friends with my friend. We both went back to our homes (him- england, Me-USA) in August. We talk every couple weeks to catch up with each other.

Situation- We were in a normal conversation and made a few back and forth banter. Then something odd happened. He randomly said “you know I was thinking, and this just shows how cool you are, you know the most about me, ya know. With my friends it’s all banter I never get serious and your the only one I ever did with”... I was completely thrown off. I thought " well this is the moment he confesses his love for me".. We talked a few messages about it and then he completely switched. He then went off about how he wants to hook up with some girl and how he has these girl problems. Im very confused on what happened? He went from being serious to being a "player". I see him in 3 weeks and I don't know if I should ask him about it. I like him, I never get jealous or anything. I want to know if he likes me more than a friend?
