Your Quick Guide To Patrick Mahomes' Family, Get To Know His Parents, Sibs, Wife, And Children

He had a clear boundary. He told them he didn't want a relationship with his mom and her kids. They thought they knew better.
A 27-year-old knew and respected her fiancé's decision not to have his mother in his life. Not once did he relent on this boundary in the 8 years OP has known him.
Despite his non-contact with his mom, her fiancé maintained a cordial relationship with his maternal grandparents. He is much closer to his late dad's side of the family.
OP did witness her fiancé's relationship improve when they started dating. His grandparents validated his unstable upbringing with his mom and acknowledged how she affected, and still affects, his mental health after his dad's death.
Her fiancé has two half-siblings OP has never met. Her fiancé has no interest in fostering a bond with his siblings and does not contact them.
His grandparents said they understood why he didn't want to be a part of the kids' lives. They knew he would not tolerate attempts at a forced relationship with the kids.
All their sympathies were fake. They hosted a dinner and invited OP and her fiancé to join them but deliberately hid that the kids would be there.
His grandparents also told the kids about the wedding and extended an invitation. His sister babbled excitedly about meeting her brother and attending the wedding.
OP's fiancé was furious and asked to speak with his grandparents. He told them they could clean up the mess they had created because he had no plans to invite the children to the wedding.
Not of this was OP's or her fiancé's fault as much as his grandparents want them to be responsible. He was honest about how he felt about his mom and the kids.
His grandparents, who validated him to mask their agenda, lied to him. It was another betrayal that poisoned any potential reconciliation.
