Believe it or not you are doing better probably then anyone I have seen on here in the last two years. Everything is happening really quick for you and you are learning on the fly. I would rather see you overconfident/arrogant then a blubbering wimp. It's not easy when your BF of 20 years since high school says "this life we have, no I don't want it anymore" and you have absolutely no say in the matter. It's destabilizing and most likely the worst feeling you will ever have in your life.
I am a big quote guy, I have them all over my house now. How about a good Rocky quote:
"It ain’t about how hard you hit. It’s about how hard you can get hit and keep moving forward. How much you can take and keep moving forward. That’s how winning is done!”
