My husbands ex stomps all over that fine line of overstepping her boundaries on a very regular basis. Sure, you need to be civil as they are the mother/father of your step children BUT come on! There has got to be a limit. Just because you share children does not mean endless support (and I mean support in every way imaginable!) For instance, calling my husband to bring her chocolate and gingerale when she is sick (insert tear drops here), boo hoo! You do not get to do that anymore because guess what?! You divorced him and he is no longer obligated to put up with your shit! He gets regular texts such as, "Oh, can you drop off a jug of milk for the kids on your way home. they need it for their cereal in the morning. Thanks babe!" Are you kidding me?! No, go get your own friggin milk!
This happened very regularily until we got engaged. Did he feel guilty and obligated to obey her little tasks? Yes because she pulled the old, "this is for your kids" card. But enough is enough already! I am sure I was labelled a "bitch" when I put a stop to it but there comes a time when an ex needs to get their shit together and move on! Just because two people share children together does not give them the right to treat someone like their endless property.
