why my crush won't reply to me via email and facebook?

[K]

i've just found out that this guy has a crush on me. he'd mention this to a friend of mine and she told me. this guy already knows that i've had a crush on him as well. i've been sending him emails and facebook msgs. i've noticed that he has read them but he still won't reply back to me. he's married as well and so am i. it's been over a month since i've last heard from him. oh, and i've only known the guy for about 2-3 months.
