My DH is a great bloke- but I had to wrest him from the 'comfort' of a seriously controlling mother!
She and I 'rubbed along' with a few 'issues' between me and DH (or fiancé as maybe he was, then) largely based on him and me leaving our jobs at 5pm Friday, driving the 3 hours up to theirs, then being coolly questioned as to why we'd arrived at 9 pm not 8? Hmm? He never said 'Because Tansie and I, unlike you, bloody well WORK and have OTHER STUFF in our lives, you stupid bitch woman'. And God Forbid we'd try and leave there before 8pm on Sunday- although I'd have to be at work at 8am Monday, 3 hours away... We might be cold shouldered for a week for that transgression (
).
Anyway, this all finally reached a head when DS1 was born. It was a difficult time for us, anyway; he wasn't a straight-forward baby and I was an older mum. MIL came 'to help' (and never, ever without her lovely but wholly ineffectual DH and DH's older, bachelor SAH DB in tow- the three of them, joined at the hip). DS howled and howled, she couldn't understand it! What was I doing wrong?? She was such a cow that eventually, 2 weeks of agony in, DH had to be A Man. He had to explain that his loyalties lay with me, not her, and that he'd support me over her if he were forced to choose, and that she'd just have to get her head around it.... Bearing in mind that at our wedding, 2 years prior, MIL came up to me and said 'How wonderful you're joining my family to which I said "Yes, but I see myself and DH as forming our own family separate to you or my parents " (so back off, woman)...
Off they flounced. what followed was a blissful month of radio silence. Then DB called to build bridges, mentioning how 'hurt' mother was- to which DH retorted that he didn't know the facts and that mother needed to respect some boundaries. So, no discussion, or air-clearing followed BUT she sure as hell respected those boundaries after that!
My DH is not a willful or 'strong', opinionated man, but when it counted, he made it clear to his family that his own, chosen, new family was his new loyalty so they'd just better accept it.
It hasn't been plain sailing; with the demise of DH's parents, DBIL (still single) thinks I am a witch but he knows better that to cite it.
Which boils down to the fact the OP has to have 'The Chat' with his family.....
