I am recently married, second marriage for both of us... both around 50. My wife's daughter, "Beth" is 28. We have dated for about a year and been married for 1.5 months. Beth almost didn't come to the wedding. We have spoken for about two minutes in our and met about three times since I have known wife. She is a spoiled brat actually. She manipulates her mom terribly. The biggest issue arose over thanksgiving. Let me describe the event. Beth and Wife discussed her driving for two hours to come see us for thanksgiving in our new home and she was to bring her boyfriend. She has a large dog. Wife told her not to bring the dog. Beth couldn’t find anywhere to put the dog so wanted to bring it. Wife was adamant no dog! Then relented. Dog could come but must be in a kennel and there would be ground rules. Beth arrived at 6 pm. Door opened bf and beth and dog came in. Dog immediately began jumping up on wife. No one restrained the dog. I was surprised that no one did anything. Then dog comes bounding into house. I again was surprised that no one restrained the dog. Wife seemed to no be alarmed by this. I was processing trying to figure out what to do. Dog running around chasing our pets, but not my place to tell Beth to shape up or ship out. We sat down to eat dinner and dog continued to misbehave. Under the table at dinner, swishing tail over food, pushing head in my crotch at dinner. No one did anything. I continued to give wife dirty looks about what is going on. I asked if I could talk to her in the bedroom and she refused. Evening went on with me in a funk over the dog. My wife was clearly angry with me as she didn’t say two words to me for the evening. Beth didn’t talk to me at all. Dog peed on carpet. Later in the evening apparently Beth was going to leave because I was such an ass. Wife begged her to stay (this was outside so I missed it). She stayed and we played a game together. Later in the night more drama and Beth complained how awkward and unfun it was and how their relationship (wife and beth) have never been so awkward and unfun. We decided to go to bed. Wife was going to sleep on the couch. Beth told wife she was never coming to house again. Wife very angry with me for not sucking it up and going with her lead, after all it is her daughter. I was angry that daughter disrespected wife, house and me. I held my tongue all night but wasn’t the most pleasant company. Now wife is still mad at me several days later lamenting how I ruined things and her daughter would never come back. That she would go to her daughters on holidays from now on. I just feel that it was so unfair that daughter took advantage of wife and me. And am very disappointed in wife for completely ignoring me, throwing me under the bus, and taking beth’s side. Ugh. If she had come to me at the very beginning and told me that daughter is just here for 16 hours, please let dog have run of house, at least I would have known and been prepared. It really hurts that she slept on couch while daughter was there validating beth’s poor behavior with dog. Not much can be done now… not sure what to do. I try to talk to wife about it and she either yells a bit or says she doesn’t want to talk about it. I have texted her a bit about what I am feeling and she isn’t interested and says that I don’t want to hear her side, I do, but she just won’t be rational and talk about it and what happened.actually
