Your prevous instructor is immature, and had/has no concideration of you or others on board. He seems to be the type that is in it for the money and flight time so he can move on. He doesn't take it serious. So the best thing you can do (as I am sure you already have) is ditch him. You are hurting him in more ways then one. He won't gain flight hours, and he won't have nearly as fat of a paycheck. Now for a starving CFI...having a smaller income...sucks!

As much as it stinks, just move on to a new flight instructor. I hope that your girlfriend/wife is ok. Hopefully you will be able to convince her to get back in the air with you...

...What a jerk...
