<human>: Can you give me the gist of the text in a nutshell?

Lenght of relationship: 1 year, 2 months

I don't know where to start but I love my girlfriend very very much. But lately we have been fighting more and more and mostly about stupid things. Also, she doesn't trust me because I tried weed once and she didn't like it but I have never done it again and that's more than a year ago. 

Lately it seems like my gf has 2 personalities, the loving one and one which hates me. When she feels down and I'm not even the reason she will actually put all her anger on me. She then expects from me to make her feel better but just can't when she does this to me. I feel like I'm dieing here. She says she wants me to break up but I don't want to.

Also all these fights are via Whatsapp/phonecalls we never fight IRL. IRL she is the most loving person I know but online she seems a whole other person.

Help me reddit, what do I do?
<bot>: Lots of fights with my gf about stupid stuff, she doesnt trust me because of something small which happened a year ago. Fights are via social media and not IRL.
