I have a boyfriend but have a crush on my friend HELP

My boyfriend and I have been together for about 1.5 years and we have had our ups and downs but he treats me very well and I’ve met his family. We are currently in a long distance relationship and I honestly don’t know the next time I am going to see him or if this is going to work out... at all since he’s moving to a different country.

On the other hand, I have gotten in more contact with a friend I met less than a year ago. I’m starting to develop feelings for him just based on our conversations. He expressed to me that he liked me and even admitted to wanting to marry me but he understands that I have a boyfriend and nothing can happen. I don’t know if he’s just caught me at a very vulnerable stage in my relationship. We are both very attracted to each other but I don’t express my feelings to him because I do have a boyfriend. I’m so confused. Never thought I’d be in this position.

Is this cheating? What do I do?
