Am I unreasonable to be upset. We can mix in a family of 3 households so me and daughters father-in-law ( both of us single) are going to daughters. I was told I must leave before tea as son in laws adult children and grandchild coming and there would be too many. Should they come and also do they need to as they are not single and alone but I will be alone for the evening. Got upset and now seems I’m not welcome at all as his children come first. What to do?
