Is it O.K. to set boundaries and distance myself from my manipuatlitive, disrespectfull stepkids?

hahaha i have no idea why the whole family is just fine with their bratty behavior!!! you have every right to be mad! i think your daughter is really mature for respecting them but she seriously has a reason to be angry...if i were you i would tell my husband how much this annoys me! im sure they feel like you're raplacing their mom or that their dad will love your daughter more ,but they have absolutely no right to tell you how important they are...you should NOT let them talk to you like they deserve better treatment...i think your husband should not be letting them be disrespectful towards you or your daughter...i would stop talking to them altogether! sadly in this situation your fiance has to either pick you or them because they obviously dont want you around...they sound like BRATS and you shoudn't let them treat you like this...good luck
