My wife won't help me with my new business so I am going to call her unsupportive.
Are you mad at her? Have you talked to your wife about this?
Yes, I have discussed this issue with her previously. The problem is she won't lend me her car to help with the move on the new business.
I don't often get to help my partner if they are in need, but I think your wife is wrong about not wanting to help you with your new business. How about you try to politely ask her next time if you really needed her help, and if she still wouldn't want to do that, try maybe divorce her and find a different wife that would appreciate you and would help you better.
I've thought that she has been a bitch for years and I am sick of her.
Well if you feel that way then it is even better reason to speak with her, do you want to keep having a relationship with someone you are sick of? Having a conversation about needing help may be the push that you need.
