Why is my son's mother so nasty and mean to me?

Well, my parents are divorced. They divorced when I was only two and a half. My dad used to be so mean to my mom because he wanted to take me from her. The older I got though, we started yelling at eachother all the time. But he always wanted to know where I was, who I was with, and what I was doing. It was kind of irritating, so eventually [Last year], I decided on my own to go live with just my mom instead of going back and forth. My mom didn’t like my dad, but she was still respectful to his face, although he wasn’t quite as nice. I think she just wants your son to be all hers? When I moved in with just my mom, my dad realized what he did was wrong and he feels really bad now, and he respects both me and my mom a lot now. Maybe you just need to have him live with you for a bit. Show his mom what she will miss if she keeps acting like that. Granted, I’m 16, and was 15 when I decided to stop seeing my dad. If your son is 13 or older, it shouldn’t be a problem at all for him to choose to live with only you for a while and see what he likes better. I eneded up staying with just my mom even though my dad isn’t so mean anymore. I still visit him during holidays and sometimes just to say hi. Maybe your son should do the same thing. See what’s better for him. Personally, I think it’s a control thing for why his mom is so mean to you. She probably feels the need to have him around to be controling twords him. My boyfriend’s mom is like that…
Hope I’ve helped =3 Goodluck with whatever decision you make =3 ~Britt xx
