PLEASE READ NEED HELP

So I am crushing on this guy named Alex, even tho I’m already in a relationship!!! What should I do? How do I block my feelings for him? And the worst is that Alex has a girlfriend!

But hes so cool and sweet and I just relate to him. Don’t get me wrong, I love my boyfriend. I don’t want to break up with him. Yet I’m crushing on someone else :( HELP
