But what can I sue her for? Getting on my nerves? Telling people at my work that I'm a cheater? I don't know...Their father isn't in the picture and their mother is mentally unstable. She only speaks to one of her children at a time and right now it's his sister...she hasn't even met her grandson...my husband speaks to his younger sister who slso stays away from his sister and mother because she doesn't want them damaging her children with their drama and nonsense.
