I'm upset with my bf for ditching me when I have the flu to play soccer
You really want your bf around when you have the flu?
He is overconfident and inconsiderate, I don't desire to hang out with him anymore or be his friend.
Just because you are sick, doesn't mean they need to spend all your time with them. They might have other things that they had committed their time to.
I'm tired of his ass. I will dump him.
You should listen to yourself, as it sounds quite selfish. You will end up alone if you think you deserve to be treated on such a high pedestal. Take into account how your boyfriend wants to spend his time while you are recovering.
