We think alike. About a month ago, when my H. brought up getting a legal separation, I told him that I wanted him to see a counselor with me. He didn't say no, he didn't say yes either. And as for the sep., he hasn't brought it up again thus far.
I hope your H. agrees to go because it is something you want and need, and perhaps it will help your situation. I am praying for you; stay strong.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
