<human>: My boyfriend[22M], Henry, and I have been friends for about 4 years now, together for a little under a year.

Currently, I am working in a different country than where we are originally from (US) and will be here for another few months (in total about 6 months). Henry and I decided to stay together while I was gone despite us not being together for very long before hand. In the beginning it was great, we talked all the time it wasn't a big deal. He helped me through a lot of homesickness and I really appreciated it.

Now, I am more integrated into the society. I've meet lots of friends and I feel very at home. A few weeks ago, I met a guy [20M] Nathan, Nathan and I have a lot in common. We get along really, really well. I started to develop a crush on him but really thought nothing of it since I'm with my boyfriend and I won't be here for much longer. Well, the crush has grown into something that I haven't experienced since I was a teenager. I really, really like this guy. We hang out often and he has expressed interest in me once, but I shot him down. We talked about our strictly platonic relationship and everything has been fine since. The thing is, I can't get this guy out of my head. I feel so guilty, because this isn't fair for my boyfriend. But I also feel resentful, even though it was my decision to stay together while I was gone. I just feel like I would hate myself forever if I didn't take this opportunity.

I guess my question is: What would you do in my position? I feel like I should tell Henry about Nathan, but since nothing has happened there's nothing really to tell. I just feel overwhelming guilt about feeling this way toward someone that isn't my boyfriend.

Can you condense the text into a few key points?
<bot>: In a (very) LDR with currently boyfriend, then met someone that I can't get out of my head and don't know if I should tell my boyfriend. I feel like a high schooler.
