39f and 45m, together 15yr married 5yr. Every vacation is planned and paid for by me. My family invited us to go to Mexico for an all inclusive, and I wanted to do something special so I paid for everything, first class tickets with express, food, taxis, you name it. He paid for the trinkets he wanted. While on vacation I briefly mentioned maybe his family would be interested in coming with us next time because they have kid stuff at the resort. He quickly and hard NO’d that suggestion and it was dropped. We didn’t talk about it after, that I was aware of. We JUST got back a day ago and he comes home from his parents saying he’d invited them and his siblings to do a trip to Florida or Texas??? We did not have a conversation about it. He is adamant we did. I asked when and he said he brought it up when I was having a migraine and couldn’t barely function laying in a dark hotel room. I have no recollection of this conversation. I feel like he’s lying to me. I asked him who would be planning the trips and he said “I don’t know”. I already know I’m going to get stuck planning. I’m so irritated I don’t want to plan it or pay anything for it. I feel like a jerk for not wanting to plan it but I seriously do not remember us having a conversation about the trips. Why would he not discuss this with me before mentioning it to his family? I told him we need to talk about it before he does any other planning and had to walk away because I’m so frustrated. That made me feel worse but what else am I supposed to do? Why lie about something like this when it could’ve been avoided by mentioning or talking about it?
