Yea exactly just mention to him once what Leo said and then never return his messseges again or block him.. also it seems as tho he’s the one who needs therapy for falling in love with someone he’s never met.. also you have it easy.. my friend is going thru the same thing except the guy lives 2 minutes from her and he ends up stalking her all because he can’t handle excepting the fact that she is just not interested in him
