No children

It's been 15 years of marriage. I still feel sad over not having been a mom to two children. He has never acknowleged how I feel (his response to my attempt to speak with him and receive any comfort is an angry "How do you think I feel"). The major decisions he has lorded over me despite my being assertive (obviously not enough) are crashing in and I feel very sad. Right now, the reality of his narcissistic personality appears greater than the rare moments where I don't have to exert an extraordinary level of assertiveness...and I'm wondering if and when it is time to leave the relationship...Anyone ever been in that difficult spot? How did you come out?<br><br>
