I'm disappointed in not recieving a gift from my boyfriend
That sucks. What would you say to your boyfriend right now?
This is complete bullshit. You should've known I was expecting something!
Though you may be in a romantic relationship, you shouldn't expect your boyfriend to always be gifting you. They may have unseen circumstances that prevent them from getting you anything.
My boyfriend is a piece of shit, I'm leaving him.
I know that you are upset, but I think you should calm down before making such life-altering decisions like this. Have you asked your boyfriend for something? He may not even know that you wanted something, it's best to talk to him about it and not expect things like this again.
