But even with a boyfriend not the kids' bio dad can be an exception although I can't think of any offhand.
Another observation I've made concerning fathers is that the father has to be really terrible to damage the children. If he drinks a little too much or has moderate bad habits like smoking, occasional pot, some bickering with spouse but not chronic, the kids still seem to feel more safe and secure and thus do better in school. Being financially better off makes a difference, too.
I think there is still social stigma for kids with single moms, divorced/never married but doesn't seem any stigma with widows. It also has to do with a child's self esteem and how they relate to their peers.
Just my opinion.
Thanks for sharing your insights. I think they’re valid.
