Many men say they have a special kind of love for their babies mothers even if they are separated.
Is this true?
Do you still have a bond with them even though you are with someone else or are no longer with that person?

Well, not the person as an individual - the mom because she is the one who carried them till delivery and then delivered 'his' children into this world. In the reverse, my dad was not a good father, but without him, I wouldn't be who I am today, or what I am today, so there is a birth bond for that reason. But many times, the dad doesn't love the mom as a person, he loves her 'because' she is the mother of his children. And many times, the child may not respect or have positive feelings towards the absent mom or dad, but they love him/her 'because' they are the mom or the dad.

Lots of men i know say this, i guess its a respect and grateful type of love?

I'm currently rekindled with my daughter's dad, but would never again with my son's dad. Although, I do see quite often a genunine look of dissatisfaction when I see my son's dad and when he sees me he lights up like a Christmas tree. I know he doesn't feel for me anymore, thank God, but this theory might have something to do with his reaction to me.

I have been married twice and still love both my ex's. The first ex is the mother of my son and I respect her for that and still have fond memories of our life together. The 2nd ex has a hold on me. She still calls me and comes over and leaves notes on the door wanting to get back together. It has been 2 years but I still can't seem to get over her.
You never know why love will do that and why people continue to hold on to something that is over, but we are all guilty.
People say you divorced her to get her out of your life, but thats not true, I divorced because I couldn't live with her. Still can;t.

It was vaguely true for me.
I raised my three alone as she had moved on, from nappy times, we parted fairly amicably although she refused all contact and paid no support. But when my youngest, our daughter, tracked her down after her 18th, my ex' rejected her cruelly, and I'll never be able to forgive her for that low act. It wrought great trauma on my daughter, and changed her forever. I had never put my ex' down, always told the kids that she really did love them, as I thought she did, and I never in my wildest dreams thought that she would do a thing like that. So, no, it's not always true.
