My girl be going crazy on me
Why do you allow her to act crazy?
I fear to put the crazy bitch down. I don't want her to bite me or to scold me.
Relationships are expected to have problems. If you feel like your partner is to difficult to handle, you should get outside help. A crazy partner might get worse if you don't do something to fix the relationship.
But I still love her.
Then you and her needs so relationship counseling. Tell her you both will go to counseling or you will end things with her.
