Allow me to change the gender in your post from mother to father and see how you'd feel if the question was asked of you .

I've seen some women posting on here that they want sole custody. Can I ask what are your reasons for this? Do you want your ex to be less involved with your children? Are you concerned with the environment your ex is providing for them? Do you want the most child support? Is it pay back at your ex? Combination of things? Just can't live without their little faces in your life?
