I had a argument with my boyfriend 2 days before my birthday because he didn't want to make the effort to take a little walk to the mall (so I went with my best friend). I was supposed to join my boyfriend later after the ride but I completely forgot to tell him (and we had a fight and he told me that I treated him like a dog and that I had done it on purpose like this was almost my birthday). On my birthday: no gift and nothing at all. I celebrated it alone with my best friend. Should I dump him ?
