A close-knit and loving family is a blessing but at the same time you need some quality time with your hubby as well as some alone time to chill and relax at home without the added stress of “Will they show up now?!”.
Talk to your husband and make him aware of your needs as an introvert as someone who needs more quality time with him alone. Another thing to do is for you guys to make your own plans so that there are some blocked times for you guys. Also, make time for yourself that is just your time. Block it out and tell your hubby that this is your relaxation time, whether you go for a massage or stay at home and take a bath. If you will be at home, all guests will naturally be his responsiblity and he can do “mehmaan nawazi” (is that the pharse?) all by himself. You just relax, listen to music/sleep/take a bath and recharge your batteries.
