In my opinion.
Relationship issues, shouldn't be discussed, or ask for help. Why? Because everyone is different, yes there are certain "stereotypes" or "patterns" ...
But you have to trust your gut.. or your heart..
Text her, but don't text her waiting for a response, don't make her feel forced to respond you.
My girlfriend is usually VERY cold on txt messages and on MSN, but I see her everyday at school, so its not a matter, sometimes she'd take 40 mins to reply just with an "Ok".. or a very short message, sometimes, she woulnd't reply.
I actually told her yesterday Im not gonna send her anymore texts because she doesn't reply, and she says she just doesn't know what to tell me next (I.E She's nervous)...
But she told me "Send me messages, I like your messages" ...
The point here is ...
Think with YOUR heart. You know her, we don't ... text her something like ...
"Its so hot outside, kinda makes you wanna take off your clothes

" ...
You're not asking her anything, she may even get a laugh ...
Don't make her feel forced to answer you, or it will put stress on you. I personally don't text unless its to set up a date...
I don't chat through txt messages, I find it silly, and stupid ... not being able to see her reactions, same with messengers...
When I text her, I tell her just a random silly fact.
I once sent her a text saying "Congratulations" to which she replied "my love, you urgently need that eye exam done, now you're even confusing your text messages" then I answered "It wasn't a mistake, I was thinking of you, so congrats!" then she said "oh thanks! if you only knew how many times a day I think of you. you'd be surprised" ...
See.. I'm not asking her anything, I just want to let her know something, and she replied cuz it was a "cute" message ...
Don't call her everyday, don't "report" yourself everyday ...
Text her when she leasts expect it ...
Soon she'll be texting you, when she starts to fall in love for you.
