<human>: Summarize the given text in a few sentences.

I posted this a few days ago but it didn't get enough attention since it was posted so late, I'm just reposting to get more opinions. I still appreciate the opinions of the two redditors in the last post though.

Okay so me and my girlfriend have been dating for just a bit over a year now, I love her, I really do. But I just don't know what to do.
Me and her met online and things seemed like they would be perfect... but some things just aren't working in my opinion. The big problem is I recently was on snap chat and was using the feature that adds people from my contact list. I was going through it and unDer my girlfriends contact it showed a completely different username than the one I already have her added on.
I decided to Google the username and found a Tumblr page of her that I guess is supposed to be secret. She has been posting nudes (videos and pictures), called a few guys that post asks on her Tumblr cute/sexy/etc, she advertises she sends nudes for snapcash (money sent through snapchat) while she does she does claim to be taken on her profile, but I still just don't like it...
There are minor problems between us like her being very rude to me sometimes, calling me names when she gets mad. Sometimes I can be hard of hearing and I ask her to repeat what she says and she gets very frustrated. IF she does something to me that makes me upset she gets mad at me and will sometimes just not talk to me.
<bot>: girlfriend has secret snapchat and Tumblr where she posts nudes and doesn't know that I know. She can have a very bad temper and can sometimes call me hurtful names and I don't know if I should continue the relationship.
