<human>: Can you give me the gist of the text in a nutshell?

We live in a pretty conservative environment, with her family being more conservative than mine. My parents know about us but her parents think i'm just a suitor who is still courting her. We have been in this relationship for 9 months now but we are currently going over a rough patch. You see, I sometimes panic and tell her what she wants to instead of telling her what she needs to. And she notices. I know she deserves the truth, but sometimes to spare her feelings, I try to tell her what she wants to hear. I don't cheat, i am loyal and faithful, but she wants me to tell her everything, from the smallest of things the biggest of things. Something i am still in the process of doing. We are currently in a fight about it, and it got to the point where she couldnt hold back her emotions and her parents heard. She tells them everything and her dad gets mad and physically abuses her. I heard it all through the phone. I do not know what happened but i heard a smack and cries of pain and sobs from the woman I love. I truly care about her and want to fix everything in our relationship, but I do not want her to continually be hurt because of my failure to tell her everything, and because of her dad abusing her. What do I do?
