Crush

So I’m 20 and I haven’t been interesting in no one lately because I’ve been through some bad shit in my last relationship but I stated working at the ritz carlton and my childhood crush that I haven’t seen in ages is working there and it’s been so long with out having a crush on someone but i legit can not stop thinking about him i never told him i had a crush on him

Should i tell him now?

I’m afraid i would look desperate but I really want to get to know him better even if it’s just as friends because he seems so down to earth and sweet

Should i risk it and ask him out?
