As a child of divorced parents I agree that regular access and non-toxic attitudes to new partners, transgressions etc is the way to go.
I am sorry James if you have had a rough time as I would be sorry if a woman also had no access to her kids.
My DP and I always argue about who would get custody..you can have them, No you! but I appreciate in reality it is no laughing matter and the situation for eg Bob Geldof was painful and ludicrous and the aftermath of all that ironic.
I think that often the idea that girls stay with mums, boys go with dads, women are the primary carers etc tis a shame that situations are always as unique as the children themselves.
I don't know. I think the idea of Hell being a woman scored and a philandering partner not allowed rights is a cliche but that's not to say it doesn't happen.
Rachel Cusk came in for hell on this forum for admitting she felt her kids were naturally primevally hers - despite saying my husband can have the kids I kind of know what she meant unpalatable though it is to admit to. Just because the visceral birthing and having them in me for 9 months means I am bound to them for life no matter what they do. But I am still a crap mum a lot of the time and believe their father to be the better more patient parent.
I do not know if you are from F4J or not - i don't care one way or another.
I asked Goldie Hawn her views on that the other day when really I wanted to ask why Bill Hudson claimed he had not been allowed to see or establish a relationship with his kids (and had paperwork to back up his fight to see them) but I was too chicken shit to ask directly.
I believe that kids need both parents where possible and in a split as much bloody support as they can get from wherever and whomever.
So yes, fathers have rights too.
But if either parent walks out when you are small, hooks up with someone else and was by their own choice a Sunday parent they cannot neccessarily decide they want to rewrite history, call all the shots and expect unconditional relationships with kids/grandkids decades later. Ultimately your child will know or find out what went down and why.
Good Luck
