Constantly pissed

Hey everyone

I'm in a relationship for 2 and a half year now and I really really really love my bf.

He is literally my heart!

But a couple of months ago it started that I don't know I felt pissed at everything he did and said and it won't stop

I don't understand why but I feel like exploding when he does anything ??

But on the other side he make me so happy I have butterflies in my stomach only by thinking of him

Can anyone help? I feel like getting mad all the time

I just think he doesn't get me often and maybe that's why I'm always pissed
