Crush problems

Rey

I asked my friend to tell this guy who I’m also friends with that I’d like to get to know him, and he said that he would and he thinks I’m a good person however he likes this other girl...

He said that he’d probably get over her if nothing happens and I don’t know what to do. I wanna get to know him more personally and try and get him to like me but I don’t know how to message him without coming off too clingy?
