I am a young active 73 yr old woman married to a 69 yr old man for 3.5 yrs and lived with for 6 yrs. we both have 3 adult children and grandchildren. They all had a great relationship until 2 years ago when Dh and his family always insisted his ex wife came to everything we did. I agree to his family birthdays etc but after 5 yrs of picking up/dropping off/inviting her to our wedding etc I said no to anything other than children/grandchildren birthday on my DH side, this caused terrible divide in the family because I ended up in hospital with AF. This has carried on and “I’m to blame for not letting ex to Dh birthday 2 years ago. Fast forward. Dh has a holiday home which we go about 4 times a year. His family join us one half term, and I have asked if my dd and grandchildren can come with me in a different half term as he he going away with his family somewhere else. He has said no! He will categorically not agree for me or my family to use this house without him, but his family would be allowed. Aibu to feel very hurt by this.
