<human>: Condense the text into a few key points

My girlfriend is the kind of girl that hates being ignored (apparently has something to do with her ex bf) I ignored her once a couple of days into the relationship and she went batshit crazy.

fast forward two months

today, she didn't spoke to me not even once, even though she was online on Facebook the whole day, I initiated the conversation as I always do, by asking her how was her day and all, she replied that it was fine blablabla... 

15-20 minutes have passed,she decides to ask me how my day went, right after I replied she tells me that she has to go to sleep because she has class tomorrow, she said good night and right after it "I love you" I replied with a heart and I logged off, 2 hours later I check my Facebook and I notice she sent a message right after that saying she regrets saying that she loves me.

I just feel like the relationship is just going downhill this last 2 weeks, and I honestly don't know if it's worth fighting for anyways...
<bot>: I think my gf is immature and selfish and I don't know if it's worth keeping my relationship with her or not
