I'm mad at my bf and I don't know why

Are you at that stage in your relationship, where every single little thing your bf does just annoys you?lol

First you need to identify if you are mad at him specifically, or if you are just mad and taking anger out on him. If you are mad at him, you need to find out why, and then you two need to work it out. Easier said that done, yes, but that's the size of it I believe.

By not being mad to him. ( Sounds silly but it has much depth if you can try to understand)

Don't worry, that's nothing out of the ordinary.

Stop. Back and look at the whole picture. By logic.

Smoke.
