Yeah, I'm just coming off 15 years of being out of the game. Definitely rusty for sure; as mentioned previously, I had that same mindset. I was unsure, thought she was the only girl for me and was down and out. It took me a while to find myself. It took me even longer to say "fukk you" and to pack my toys up and leave.
The two biggest lessons I learned is: 1) Never let her see you sweat/or display that you can't live without her. 2) nikka, you got options, you always have options. When a bytch wanna act up, call that audible and go play the 'read option'. You're the master of your fate - not her. So don't give her that mental power over you no matter how dire it gets.
