I've always thought my MIL and DHs relationship was a bit odd and over close and I don't know why it hasn't occurred to me before but I've just had a sudden realisation that she uses him as a husband not a son.
From my point of view their relationship is really affecting our marriage but how on earth do I say that without sounding like I'm making him choose, me or her! We've had a bit of counselling and the counsellor said that perhaps he has the relationship with his mum he should be having with meas his wife. How do we all move forward?
