I grew up with a similar situation, although my dad was not abusive in anyway towards my mom, my mother had ill feelings towards him and therefore did not appreciate my closeness with my dad. I think your child is just eight y/o and they do not understand and nor will they if you try to explain it. As they grow, they will eventually learn that you were their provider and always will be. In the end they will come to you first for support when they realize who their father is. I am sure the reason they "get what they want" is because he is either making up for not being around by buying them things or he is doing it to keep them quiet and happy. At your childrens ages they dont see the pain and effort you go through because it is something you do on a daily basis because you are their mother and have to versus his once in a while parenting. Just know that you are clearly a good mom and kids will say things without the intention to hurt you, they dont always have the ability to think before they speak and if they do - they might not be aware of how painful their words can be. Be consistent and that will be the best for all of you. At your home they expect rules, etc and at his - well - I guess I dont have any real advice for that. Sorry.
