So, here is the situation.

I call HB Saturday, she doesn't call back. I call Monday at 14.00, she doesn't pick up. Immediatly send her txt. she txts me at 19.00 that she was in the mountains and didn't have signal
I didn't respond, freezeouted her.

Wednesday, she sends me sms at 11.00 saying i should contact her. I didn't. She send me text at 17.00 asking me out tomorrow. I text her back at 20.00, unaffected with "I'm not going to city tomorrow ". Immediatly get a text with shit test: "After all that time not responding to me, you write just that? Thanks alot.".

I respond: "Stop bitching. Almost missed my train in the morning and till now didn't have a single minute free. But fortunatly, it's over."

She texted me back, wanting to initiate conversation, but she was clearly insulted.

I asked her "Why are you in a such a bad mood today?" and got the txting going.

So today I initiate txting with my HB in interest, and she did the small freezeout on me!
I sent her txt at 17.00, saying "I have another busy day but here is one sms for you so you won't be in the bad mood again. Hope you have more relaxed day. Enjoy."

I wrote her text which didn't expect her to responde, since I already knew she will not respond in ideal way.
Anyway, she send me text at 23.00, something like: "I just came home, I'm ok. And my phone dieddddd. We'll talk tomorrow. (not in a way that we NEED to talk about something)"

I couldn't decide if i should reply or not.
I went with the "Ok. good night:)"

As for the background: She is a good friend, I screwed up because we made out and now she requires some handling like this from time to time. Oh yea, and she has a boyfriend, for almost a year now.

I'm not asking so much for this specific case, but everytime, in situation like this I never know if i should respond with that short (Ok/good night/see you later) or not. And I mean replying on txts that don't have explicit or even implicit question.

Any input would be helpful.
