BellaOnline Forums Family Step Parenting New house

Hi All, Sorry to be a pain. i need some outside input. we are a blended family, me, dad, dear ss 19, dear ss 15, dd 5 have been married to their dad in 2001, have known them since they were 4 and 8. we get along well. i am too rigid at times, i think its the teen stuff getting to me. the boys live with us 1/2 and 1/2 at their moms. we are getting a bigger house (after 10 years, yes!!) master has an ensuite, second bedroom has an ensuite too, 2 other bedrooms have a shared in between washroom access from hall. Must the oldest child get the second master? my argument is that they are only there part time. his argument is that he is the eldest, he should get to choose. Am i being unfair??? he is off to university next fall.
