I hear you man, I hope my son never feels this way as well! It's unfortunately what I've had to deal with for many years.
Without going into too much detail, I'm not the twinkle in my moms eye so I haven't received similar treatment as others have. Even more so because I'm far more independent than they are; I don't ask for help, I'm not an ass-kisser. Coupled with the fact that she abhors my wife, we get treated real swell!
The best thing we can do is instill our loving values and qualities in our children so that when they grow up they don't feel the rejection and disdain we did.
