I can tell her I won't put up with calling her boy friend from the house. Then she'd probably call him from in front of me. Or she would just say "whatever"...
then you boot her a$$ down the highway.
Love is one thing.
BUT. being openly disrespected and ridiculed is cruel. and foolish to allow yourself to be exposed to this.
Why do you think she would act like that, while you proclaim your love to her?
