Why are boys so confusing?

So I’ve been talking to this guy since November 2017, he’s friends with a guy I live with and is in my course in college and he got my Snapchat of him and that’s how we started talking. We get on really well cos we have a lot in common cos we’re both into farming and that’s his job atm. He’s doing part time college 3hrs away from my college near where he lives so we’ve only met once cos it’s hard for him to just take a day off when it comes to his job which I completely understand cos that’s farming. He always kinda hinted at coming down to see me at home which is 3hrs from him as-well and it hasn’t happened which I’m kinda ok with because that way I don’t have to introduce him to family. But from February onward we started calling each other him calling me mostly cos I don’t know what time is best for him and at the start it was just now and then but near the end of March it became nearly an every day thing cos he wanted someone to talk to about a family thing and he was comfortable saying it to me which I was delighted about some days he’d even ring me twice just to talk about random things and he’s always a great laugh and able to cheer me up.

so easter Monday we’re texting away on Snapchat like usual or just sending random pictures of what we’re doing every few minutes and stuff and then on Tuesday I was going to France for a college trip and for me it’s different because I’m the only girl on the course in first year and there’s no girl in the 4th year class so I was going abroad with 20 boys all near my age which doesn’t bother me cos I prefer being with boys than girls but anyways as soon as I got to France the guy I’ve been talking to just kinda starts ignoring me for some unknown reason like he’d open snaps and just ignore them even ones with writing which annoyed me cos it was all fine the day before and then I thought maybe the guy that introduced us was sending pictures of me talking and sitting with other lads which pissed him off which turns out it not that cos they haven’t talked to each other in a while (they’re just that kind of friend) but even now that I’m back I still notice things are off like he hasn’t tried ringing me I rang him once to see was he up for a chat but he could only talk for like 5mins which usually our conversations are no shorter than 15mins and he hasn’t tried calling since I know it could be said I didn’t call him again but I don’t want to seem like a pain in the butt. Anyways I feel he might be with another girl at home which is understandable and I care but it doesn’t bother me too much because we haven’t defined the relationship and the long distance (it mightn’t be long to some but where I am it’s a long distance) isn’t helping our case but why can’t he just tell me if there’s something going on cos I don’t want to be waiting around for something that isn’t there (we’ve pretty much admitted we have some feelings towards each other but I take my feelings very slowly these day just so I don’t get hurt again) why should he get to be with other girls if I’m being good and keeping away from other fellas even when we don’t really have anything going on. It wouldn’t be a problem with me if we were just friends for now and maybe even leave it at that forever but I don’t want him just out of my life cos he’s sound and would be nice to have around but if he’s going to pretend nothings after changing and not telling me if something going on with someone else I don’t know if I should keep him around. What do ye think? I know I just wrote and essay there but I kinda needed to be explained first I think. Also I did mention to my housemate about it but he doesn’t know and he kinda likes the thought of us together it’s seems but doesn’t want to get involved with any of theirs but agreed to tell me if he heard anything because he understands I don’t want to be played cos he’s kinda facing something like this too. Do ye think I should ask the guy straight out what’s going on or wait another few day?
