My son is 30 years old and we historically had a very loving and close relationship. Over the last 4-5 years he got involved in a relationship and just this last summer got married. Since he has been with this gal, he suddenly questions and debates me on almost everything and is stressing me out not to mention the disrespect. Most recently I had an ornament exchange pre-holiday party with just my gal pals and invited my daughter-in-law to attend to hopefully bond. My son was very offended as to why he was not invited and did not understand why it was for only ladies. My son and his wife both disagreed with me and didn't understand why it couldn't be co-ed. At the end of the day, I told my Son he could attend, then the day of the party, neither showed up. Please help me understand how I could of handled this situation better. Thank you.
