Me? No. My DSIL is a great guy, but his family, not so much. He and DD offered to pay his Dad's way home if he woudl come. No. Mom was not interested, when DD and DSIL talked to her about the wedding. Paying for the wedding was between my DD, DSIL, my DH and I. DSIL told us his family would never offer anything, but that it was more about him than anything else. I had known DSIL for several years before they married, so I had observed as much. So no, I would never have approached his family about any kind of payment, even if DH was not old school in regards to esponsibility towards our daughter.
When my DGD was born his Mom came to the hospital, but said that was all that she would do. She would wait til DGD was older to get to know her. That day still has not come 15 years later.
DD and DSIL maintain a superficial relationship with his family, but as a parent, I refuse to widen that chasm by pointing out issues, or magnifying them. I love my DSIL and know that if I did so, in the end only he and perhaps my DGD would be hurt.
The reason I shared this was because I think that parents need to be careful when their children enter into relationships. It is easy to pile on MIL and feel that you are one upping that family, but the truth is that your child, your grandchildren are going to be part of that family. I would smooth that path rather than make it more rocky. In the case of the OP, I would like to think that I would encourage my DD and DSIL to find a date that is a better fit for his family. Does this mean I woudl ask them to wait a year? No. But I sure would try to find a compromise, and if that meant that the athlete needs to compromise a little, so be it. I have always tried to help my DD find a way to make things easier for her DH with his family, and if his Mom or family was still difficult, then I knew that I had not compounded that problem. I think MOB should try to do so as well. Her future DSIL may be telling all who listen that his Mom is difficult, but he may be still wearing rose colored glasses. Eventually they come off and this couple will be living in the World they created, with a DDIL DMIL war raging on. And we will be eading about it on the DIS, Fisk will be saying this is a marraige problem. Ane they are right. The wedding is over, and the marraige has begun.
DD and DSIL are married now 15 years, and the MIL has been proven wrong on all counts. No abortion for my beautiful DGD, no divorce for my DD and DSIL, no crash and burn for either. They love and respect each other, and instead of avoiding DH and me, they gravitate towards us because the only agenda we have is to support them in their lives and marraige ,not come between them by tying to cause a divide.
