It all comes down to making peace with ones self and being able to live comfortably with that choice. I'm glad you were able to do this although I don't think figuring out one's problems drunk is too healthy
Liquor lubricates the brain. I've had many an epiphany while drunk or stoned. But then again I also invented the fork a few centuries too late while stoned. That pissed me off.
The answer, Rodja, is deal. Do what you have to. You might need to love her now, and in a year you might not give a **** if she drove off a cliff and blamed you. I've got ex's I wouldn't want to live without who are great friends now, and I've got some that I'd seriously consider strangling and burying in a shallow grave.
As per workouts, take the most intense emotion at any given time, whatever it is, and channel it. Love, hate, frustration, horniness, whatever it is, you can grab hold of it and shunt it into your workout. Horniness is the most fun I have to say, especially if you're with a girl and she's around when your done. I got a friend who I'm interested in, she wants me to join a gym with her. Can't wait to see her get all sweaty.
But, she's into the Planet Fitness type of gym. I'd rather sit in lemon juice and saw my balls off than set foot in there. We're still looking for a compromise.
