I see so many posts, shes really not a SM, because they are not married. (and many cases, they live together- not talking about cases, where the girlfriend has her own place.)
Well if your new man and his x weren't married---but had children does make them NOT the dad or mom, because they weren' married?
Ithink the situation defines its self- it comes with commitment to your SO. Married or not We live together. BM and DF share a child. They were never married. THANK GOD LOL. But does that discredit her or him from being their child's parents? So why should my martial status define if I am SM or not? I am not big on titles, but it seems the title is important.
