Quote: One problem, I need to have a talk with my MIL regarding my job and whether I need to begin looking for a new job elsewhere. She'll be back in town late this week. I'll see.
All right. If no one else will touch this, I will.
How about you make your own decision about whether or not YOU WOULD LIKE to find another job?
All you owe MIL is your 2 weeks notice.
My honest opinion is that you should get another job. Your wife, at this point, LIKES that your co-workers tell you everything. So remove yourself from that environment, with no hard feelings and NO FRIGGIN WHINING OR EXCUSE MAKING. Just quietly apply for and get another job. Put in your notice as if it were any other job. Then leave. I really think that would be a step in the right direction. At this point, I think that in your wife's mind you are DEPENDENT on HER MOTHER to support your family. That just doesn't seem very manly, no matter how much of your own weight you pull.
