I want you to stand up to me. Don't allow me to put you down. Don't make excuses or explain your situation......but stand up to me. Talk back with a firm confidence in who you are. (And there is a difference in being an a$$ and having confidence.)
She doesn't want a nice guy. She wants a strong man who will not take any of her stuff. The man who will face her and tell her where she can go...and act as if he could care less about her....will be the one she will probably want right now. Makes no sense to you, does it? But, I'll bet you that will be what she'll do. Her priorities are all messed up. Her natural desire for a strong leader in her R, and as the father of her child, is there inside of her, but she's gotten everything out of order.
I think you need to get away from her and stay away for your own mental health sake. You did not want the R near as much until she walked out. Now you are completely obsessed by it. That is not healthy. You have so much work to do on your own growth before you have a future with her.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
