S.O.
WOW! I am not a grandmother, but I sure do feel the pain in what you write.
Please do not take offense to any of the following, but let me share my thoughts with you about my kids 2 grandmothers. My mother -in-law shares her opinions very openly and boldly about everything. She speaks very freely about what my children wear, how they eat, and when they were small, she had very vocal opinions on books they should read and what they should play with. Once we went to restaurant for breakfast and it was very crowded there that day. There were 9 of us (2 in highchairs) packed into a little 8 top table while we tried to eat. One of my nieces started to cry.
My MIL insisted that her mother remove her from the restaurant immediately due to the disturbance. (It wasn't a screaming fit...she was crying a little). It was raining and 40 degrees out.
Later, my son dropped a grape from his plate. It rolled under the table where all the legs, feet and diaper bags were. My husband looked down and tried to find it. hopeless. My MIL told my husband that my son should get down there and pick it up. "You cannot raise a child that won't pick up after himself."
I cannot tell you how unpleasant our visit was. We are not bad parents, but we don't do things her way or on her timing. We now only visit them for 2 -3 days max once a year. And we are hundreds of miles apart.
My mother (and I am not trying to be biased...just giving events) will ask me or my husband, "what time should the kids go to bed?" "What should they eat and what do you not want them to have?"
"If they go out to play, what jacket do you want on them?"
My mom knows how to do this stuff---she raised 6 of us!!! But she asks instead of making demands or commands. My parents are also hundreds of miles away and we always look forward to our visit to them or vice-versa.
Maybe your new son-in-law feels you are still in "raising a child" mode. I know you are very hurt, but re-read your last sentence. That might be the thing they see most about you. It's just a thought.
Your help was very valuable to your grandson when it was needed and you sacrificed a lot to do that.
Be thankful for your time together and let the memories be happy.
Try to repair things with your daughter and her husband so that you can be present in your grandchildren's life.
Sit down calmly and talk to your daughter at the next opportunity. "Strike when the iron is cool" is one of my new favorite sayings.
You mentioned emotional turmoil for 29 days. Were you visiting that long?
If so...way too long a visit. People really start losing patience with guests after 6 - 7 days. A 7 day happy visit is so much better than a miserable long visit.
You can't do anything about the controlling husband, but you can change your approach. And be there to help in the future and love your daughter and be there if there really might be alcohol problems in the marriage.
God Bless.
