<human>: Can you summarize the given text in a few sentences?

Hello,

I have been dating BF for 10 months. Whenever we go out, I try to pay for half the dates -- I let him pay once, then pay the next. He never asks me for this, I offer myself. I try to keep things 50/50, but don't really count to every dollar.

We went on vacation. We spent equal amounts on entertainment/food/etc at our destination. Then, when we got back I gave him back ~50% of the plane/hotel costs. 

Now he tells me I owe him $130. I realized that he is right and I miscalculated, but I am extremely offended that he counts the money to every dollar. Now I am questioning his feelings for me. I think that if he truly cared about me and saw this as long-term relationship leading to marriage, he would not be keeping score like this.  

Is he being reasonable? Am I overreacting?
<bot>: I think he is being cheap by asking me for exact 50/50 considering I have always kept it like this voluntarily. Is he being reasonable?
