Here is my advice, record record record- voice and camera both. Do it secretly.
DO NOT GET HER PREGNANT!!!!!!!!! If push comes to shove, you can always file for divorce and use the recordings, rather than waiting for her to put false harassment charges on you.
I hate it when folks have to go through all this. But this is real, and we see tons of cases like these. It always follows the same pattern- she will hold on to an issue that involves ‘injustice’ to get parents by your parents, then grill that issue, then distance you from your family, then have children, the unhappy life takes full root and the man is miserable.
