Is it normal for a mother to choose a man over her biological child in any cirstance?

don't know if ya truly want to hear this but....your step probably sees your mom coddling you when you should be doing things for yourself, of course age-appropriate & such (not picking on the co-sign, but most likely all the other LITTLE things that have been going on);; you ARE, in fact, putting your mother in a position of having to chose by the way the other 2 of you don't get along;; you love your mother, it's about time you start doing for her..if that means faking like you get along with him..then do it for her;; SHE,my dear, is the one walking on eggshells, not you..you're just prancing along letting her still do for you;; get along with pops, there will be no strain on any end;; you are just feeling the repurcussions from your mom being placed in-the-middle of the game the other 2 of you are playing...help her out a little...give her some peace...quit fighting with him & start working with him to make your mom happy...about time ya give up something, no??...just my input...
