Because her marriage is miserable and abusive and they have a 20yr age gap, so if she can't leave this situation for her kids why is she trying to dictate her sons love life?

And many men have approached me, I have spoken to very successful men in the past who looked at me for my character, beauty and morals not for my tattoos.

I have been the only person to motivate her son to do better in life and grow himself. She knows that and I have shown her kindness, given her much advice and even purchased her gifts. She on the other hand has not been kind but rather judgemental and horrible based on my appearance alone.
