Should i sent message to her?

There's a random girl in facebook, don't know each other and never meet before, Always i message her 1st since last month, she sometime reply me and sometime not, she liked 1 of my photo last time (random photo that i captured) , i usually liked her photo but never commented. She is the person always like random stuff photo, status, post by other people and she rarely comment to people things. Recently she seem ignoring me and other people (what i seen is other people commented on her photo or status, she no reply most of the time) . That i message her "Christmas Eve to you", she seen but no reply. She always use iphone to online facebook. She on and off FB sometime maybe she just checked her notification or message then off again. But she got post new photo today, got people comment and she also ignore.

So i her a greeting on Christmas day also no reply, but if were last time, she at least will reply

Should i send a message to her about say sorry being disturbing you and i will stop to message u?

Any other idea?

If I were you, I will send a mesage.

You shouldn't. It seems she just thinks you are a friend online, not that into you.Don't waste the time on her.

Personally i'm one of those girls that hardly ever replies. Don't message her. You might get a negative response. If she cares she will message you first. If not then just leave her be and find someone better
