Pushed too far?

Things only got worse with LDB. Let me rephrase that: I MADE things worse with LDB.

The anger I felt from the week he was in NY spilled over into the following week, mixed with severe PMS and baked-up into an unhealthy BAD ATTITUDE. He finally called me on Tuesday - twice. I didn't answer. I was pissed and sent him directly to voicemail where he left no message.
I didn't call him back and my attitude sank even further.

Finally, I texted him Happy Thanksgiving on Thursday and I received another curt reply: "U2".
Wow... thanks.

Today I broke down and texted again: "Did I piss you off?"

I got a phone call back that started with him going off on me that I need to see a doctor because I'm crazy. That he called me three times and I never call him back. He said he thought, "Maybe she's in class or maybe she's away for T-giving..." but when I didn't call or text, he decided that's it, he's done. He thought about where I was. I want to cry now.

He forgot himself for a few minutes and told me about his drunken T-giving with his friends... but he was detached again by the end of the short call and sounded like he didn't care whether we talked again or not. I got in the shower and let myself cry.

I am afraid that I have blown it once and for all.

My brain is working overtime coming up with what to do next. Do I start calling and paying him attention? Pretend none of this happened? Explain to him why I haven/t been calling? Move on and forget him?
What the hell do I do now???
