<human>: Can you provide a brief rundown of the text in within 3 sentences?

Me and my girlfriend have been together for 3 years now. And I have been thinking about how this relationship is working out for the last year. 

We meet about 3 years a go when I was working full time at my birthplace with all my friends gone studying in another city. It was a terribly dark period in my life when thinking about dying was a daily part of my life. After we meet things got quite a lot better and I have learned to live with and handle my issues.

Now, for the **problems**:

* We argue a lot
* These arguments sometimes turn into breaking stuff and domestic violence (we're both bad here)
* I have cheated, twice
* I suspect she has too, caught her having received money for showing herself on a webcamera, and caught her lying about phonecalls when she was away for a weekend
* I feel like I'm taking precautions to not piss her off everyday
* Both of us feel attacked when we're talking about normal things with eachother
* We got almost nothing to talk about anymore

Well that's a summary some of our "issues", I feel quite bad just writing this. And I'm a bit afraid what answers I might get from this. 

I think I love her, but when I see my friends relationships or at least how they talk about their girlfriends I begin to wonder wether  this is unhealthy for me and her.

So I guess my question is, am I in a really unhealthy relationship that both of us should get out of, or should we try to work on it to fix it?
<bot>: Me and my girlfriend for 3 years argue, fight, cheat, lie and been violent with eachother. Should we break up or work on it?
