Ideas on how to save my marriage from divorce. Real answers please!?

Time to cut momma's apron strings. As long as she is "calling the shots", you are stuck. About 46% of marriages in the US end up in divorce. If HE filed for divorce, what are the "grounds" ? So, just tell him. "It's me, or your mother" ! I went through a similar divorce; My wife went "hay-wire", so I packed up everything in Chicago, (including the 14 year old girl we had adopted), and came to Texas. My daughter is now 41 years old, and doing well ! Good luck !
