<human>: When I met her about almost 2 years ago I wan't looking for a particularly "serious" relationship. Surprisingly I fell in love madly even though she warned me of her "difficult" character but at that time I didn't care that much. 

Actually I had to try pretty hard to convince her that I'm the right guy. But now... I'm remembering her warnings all to well. The thing is that we virtually don't fight. When we have a disagreement or rather if I do something wrong she just shuts me out and goes all quiet. The only thing I can get out of her are sarcastic remarks. 

Surely I'm not perfect but recently I think she really starts to over react. For example I used to work in a music club. Sometimes the manager calls me and asks for help on really big gigs. We are short on money right now so when he called I agreed without hesitation. Especially that we were supposed to go to that concert anyway. When I told my gf about it she decided not to go because she won't have nothing to do for the first part of the gig and so I went alone. When I came back I got the cold shoulder for leaving her alone for the evening and she even posted on her fb something like "oh yet another lonely evening". 

That's just one example and alll in all I've reached a point where I'm considering breaking up. She had a rough childhood and last year wasn't easy on her as well but I want to be happy in my relationship. 

The thing that screws my up is I don't know what to do... If I should keep fighting to make this thing work or just say enough is enough... I know there is no simple answer to that question but would be really grateful for some advice.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Gf gives me a cold shoulder more often than I think I deserve. Not sure whether to break up or try harder at making things work.
