Search Results: using friend to meet people

I met a guy on Tinder (we are both over 30) and we`ve been dating for 2 months now. We were both quite clear we are not into hookups but more long-lasting relationship. We`ve had exclusivity talk and he said he is not dating anyone else and doesn't want to. He was very specific about he is not playing games with anyone and doesn't want to ever. It is a long-distance "relationship". Because of that we`ve spent only few weekends together since we`ve met. Because of his job his residence is only temporary (he is from other continent and is basically very lonely in a city where he lives, because he even doesn't speak the local language and doesn't know many people there). In couple of months he will move back to his home country which will make our distance much greater.

Communication is going well, he is nice, sweet, supportive, caring. Everything is good. He said he likes me a lot. Couple of times early on he mentioned how would be nice if I could visit him at his home town (when he goes back). We always spend an amazing time together. Lots of laughter, jokes, doing stuff we both like, great sex, etc.

BUT: I noticed he is changing his Tinder bio occasionally (and also pictures). Just writing about himself, not saying anything about what is he looking for.

I dont know how I feel about that. Some of my friends say they use Tinder when travelling to meet people for drinks and dinners (even though they have partners). I dont know if I should ask him about it or not. I think it would be best to do it in person, but we will not see each other for couple of weeks more. Should I do it over text? Or I should just let it slide as we are still early in dating phase?

What do you think about the whole thing=
