<human>: Can you succinctly summarize the text in 1-3 sentences?

So both me and my gf (both college students) went home for the break, although she was going to stay a few extra days of the semester. We were friends for about two years, and in a pretty intense, sexual relationship at the (mid-December) start of the break.

Anyways, we chatted on WhatsApp almost daily for about two weeks, until after New Years', when our school started releasing grades. Both of us had some poor grades, and I made some stupid 'jokes' about not feeling guilty about doing better than her, which hurt her and I apologized for immediately. We continued talking.

Then a week ago Sunday, she says BRB mid convo, has to do an errand. No response for two days; her WhatsApp isn't even logged in. I fire off a quick "what's up?" on Tuesday, again no response. Finally I send the same message on Facebook Wednesday, she says her phone was turned off. We exchange a few messages, and then radio silence. Dead silence. Remember, we've been talking daily practically since September, texting when we don't see each other.

She came back yesterday (Sunday). Her WhatsApp was online. I sent her a message in the evening explaining how I felt and whatever was up, I'd at least want to talk it over with her. About two hours later, no response, I said 75% truth, that her breakups are poor, but I still want to go have coffee with her.

I feel like I've been overbearing, but this has been very emotionally difficult for me to cope. It's a relationship purgatory, where I don't understand if/why she wants to break up with me, and why she doesn't attempt to say it directly, or even contact me at all.

Have I done the right things or am I just a clinger at this point? Is there anything else I can do?
<bot>: Lots of conversation away on break, when suddenly, very little communication with gf. Can't tell if she wants to break up and why she doesn't attempt to talk to me at all, if the former is the case.
