Caution! Distance won't do jack if she is still mentally wrapped up with them. I've seen young wives spend 2 hrs on the phone each day with their mother ... it isn't healthy and never ends well for the marriage. (I say "young wives" because they either cut that out, or the marriage fails.) When I was dating 30+ years ago (thankfully, before I proposed), I made it very clear to my (now wife) we would need to put our relationship and communication between us must stay between us. That her over sharing would be a deal breaker for me. She was one who had a close relationship with her mother, so it was natural for her to share "everything". She understood / agreed and we setup some guidelines. She created some distance and prioritized our relationship over the one with her mother. Now, her parents are in their 80's and live next door (literally) and it's a great relationship. Her mother has learned to respect our boundaries and - in turn - we can help them in their old age.
