I would. I would tell myself when I was 18 that my mother could be a horrible bitch and to get on my guard then so that I could have been more prepared for the bullshit she put me through.
Be more receptive to C back then so we can work through this bullshit early instead of dealing with the kid issue so close to a biological deadline. I'd rather have spent my youth with a man who was responsible and loved me instead of with a man-child who took advantage of my fear of being alone. Hell, I would have had C's kids, too, if I had worked through all that early enough.
