Shoud i also reply her like this!!

What do you think “hm” means?

Nothing its just a sign of ignoring like a one word reply

You are being dismissed - sent away like a bothersome child.

Stop wasting your time with this rude girl.

if you want her to block and forget you that would be an ideal response. if you want a future relationship with her just question the intent and rationale for this curt response.

BTW - never follow guys recommendations on a female problem as will be disastrous.

Please don't make assumptions and read too much into a single reply and interpret it as some kind of 10000 word manifesto. Give her the benefit of the doubt. If she's in fact ignoring you or somewhat perturbed by what she thinks you're saying or doing, it's up to her to explain thusly. Remember that she has a life beyond chatting. Maybe she has other issues that somehow managed to influence (temporarily or otherwise) this SOLITARY post and nothing else.

Treat her with respect. Take the obvious high road. If she's a good person, you'll might get along and keep this thing going. If not? You're the better person in the equation.

Sarcasm (hopefully this is the case here) ain't going to help this oblivious bloke.

Maybe she is busy or have work. Just discuss what you feel with her.

I used to get involved in chats. Sometimes, there is nothing left to say. Some just go away, some say 'bye', and maybe some just say 'hm'.
