My son and DIL have been married for 3 years now and they dated for 8 years before that. Son (36) DIL (32). I have what I always considered a great relationship with my DIL she is very involved with the family always texting to ask how family members are doing if there is any issues that arise and she takes a true interest in the family. I have 2 younger sons as well. Both not married.
I have always taken to my DIL and she is great for my son and I truly care about her. My long term bf and I live 30 minutes from my son and DIL.
My son has been working super hard lately and just as his mother I wanted to give him a check and specify to use it on something just for himself (they have no kids) and I wasn’t meaning it as don’t spend it on your wife rather I just wanted to give him something special to treat himself. I understand they are married blah blah blah and that you should treat them as a unit and if you do for your son you should treat the DIL equal which I always do I include her in texts about my granddaughter (their niece), when we go away I include her in the text updates of pics, we text usually 1-2x a week. I would consider us close. Well this one time I wanted to do something special just for my son when 98% of the time I include both of them because he is still my son and ever since then my DIL has been very cold to me. Not initiating any texting which it’s pretty equal, she didn’t come over when my son did last week for dinner, and when I do text her it’s one word short responses.
I asked my son about it saying I’m very hurt by her lack of communication all of a sudden and my son confirmed it’s due to the check and she feels hurt that she wasn’t included. I think it’s a little ridiculous when I include her like I said just about every time so she is going to begrudge me the one time I do something special for the son I raised?
Am I wrong and out of line for not budging and including her in the check and standing my ground that I have a right once in a while to do something individually for my adult child?
Am I required to treat my DIL exactly the same as my son to a T in every sense of the word?
I understand they are married but does that mean I am no longer allowed to do things individually for my son?
Should I reach out to my DIL to clear the air?
What should my next steps be?
