One night stand

I had a “one night stand” with one of my friends brothers and I told my self no strings attached but guess what now I really like him and I have liked him for a while since before we had sex but it was kinda awkward just because we didn’t know each other very well and now I just really want to tell him how I feel but I don’t want to get hurt. He has also mentioned not wanting a relationship this year with anyone. And I’m okay with that but I just want him to know how I feel but I’m not sure if I should.
