<human>: I [28M] has been dating the gf [28F] for almost 2 years now. We have our up and down but nothing I couldn't over come. But lately I have been noticing some issues that I can't over come. 

We just came back from Las Vegas last month. The trip was paid by me and when we went out, I paid for almost everything except 1 time at  the noodle house. The problem started to occur when we started to gamble. She took my money to gamble, when she lost = our loss, when she won = her winning. (Keep in mind, her income is slightly more than mine. So no, I am not a sugar daddy).  And then when I won on my own, she asked for a split. a couple days later she won a whole lot, I was wonder if she can spot me back the amount that she took from me to gamble. She started to say things to belittle me like "what kind of man asking for money." 

She broke her phone. I got her a refurbish iphone 5s while waiting for the 7 to come out. Now that I pre-ordered her the 7(it's for her birthday), I asked her to give me the iphone 5s so I can give it to my my aunt. She again belittled me telling me that a man should do this and should do that. 

I feel like I have enough of this and thinking of ending it with her. The belittlement bothers me more than anything. Am I being petty or cheap?

Can you give me a shortened version of the text?
<bot>: GF gamble with my money, claim the loss as ours, and winning as hers. Took my loaner phone even I bought her a brand new iphone 7. Belittle me when i bring up the issues.
