To the OP, I am late to this thread, but I want to say that I have empathy for your sadness. I think it is part of the extended empty nest, when the adult children can no longer be with us for holidays. I think that your son may have been indelicate, to say the least, in his communication with you. However, don’t take it as a knife to the heart or whatever extreme thoughts you may have had. Try very hard not to take it so hard. You will help yourself. I do think that at a more neutral time you could ask your son why it is necessary to always go to inlaws etc. You are entitled to say that you wish they could be with you on occasion, but you should be very careful not to go too far. I can pretty much guarantee that if you get bent out of shape, rather than rational, it will not go well for you. Also I was glad to see that you had your other son, DIL and grandchild.
This thread brings out a lot of positive and negative feelings that people have concerning extended family, holidays, obligations, respect, etc. I had my own very rough introduction to this from my then future MIL for a particular holiday decades ago when I first was engaged to her son. I never take well to demands, and her performance (complete with a diatribe in her native tongue), will not be forgotten by me unless I become senile. My inlaws continued to demand many things that concerned holidays and other family occasions (involving their family, never mine). They could have cared less about my feelings, my mother (Dad had died years before), and really to be honest, my husband’s feelings (their son). They certainly had their limitations when it came to balancing what they wanted with anyone else’s needs. Also, even though we spent countless holiday, birthdays etc with my inlaws, MIL always continued to lament how her Daughter was not there. (Her D moved across country and was rarely available for her - can you guess why?) However, now that they are both gone, as is my mother, we do miss them, warts, diatribes and all. I only wish that I would have had the presence of mind, years ago not to let it get to me.
For the other posters on this thread, I have to say that a few things on this thread really cracked me up. No guilt trip at all to say that you carried the kids for nine months, so they must do what you say! LOL! Children do not ask to be born. You dragged them into this world screaming, and do not get to make them beholden to you until you die. You may believe that you get to do this, due to culture, family background etc, but this is boundary disorder beyond belief. If it works for your family, so be it.
BTW, people do resent doing things that they do not want to do. This is normal, not dysfunctional. Now of course, there are many things that we must do that we do not want to do. Many people take ***! from their bosses so that they can earn their salary. Many take it from their spouse or SO, when it comes to the in laws in order to have peace in their own home. The real key here is to not have the family come because you will pitch the biggest fit if they don’t. They should come because they want to come, and because it does not require superhuman effort. Expecting superhuman effort is unreasonable. Also, if people must tiptoe around you because you will blow a gasket if they don’t do what you want, I can pretty much guarantee that one day, they won’t be able to please you, and you will blow a gasket.
