My partner’s family are coming to visit from overseas for the first time. We don’t live together and my place has more space to accommodate them so he asked me/I volunteered to host them. I’m having to tighten my belt at the moment but he will buy the food and drinks and says he’ll help get the house ready etc. While they’re here they’re all going to the Chelsea flower show for the day. I love gardens and he knows this. He’s not that into them but likes them enough. I recently found out that he’s bought himself a ticket to go with them. AIBU that I feel a bit miffed that he didn’t think to invite me too and buy me a ticket, given that I am hosting them all at my house and I am having to watch my spending?
