Advice needed!

[JThiessen]

Sounds to me like you need a kick in the ass to get yourself out of this funk you put yourself in. Sounds to me like your wife has every reason to put your butt on the short leash for a while. If she hasnt, be very appreciative of her.
For RC's, I'd keep your wifes Slash and your Revo. Sell the rest (50-60% of value), all the batteries that dont support those two, and start looking at either a Summit, or a cheaper option, an AX-10. Also, figure out why it is that you dont seem to get along with other RC'ers...and go make some friends/aquantinces to bash with.
