My boyfriend doesn’t have plans for us on Valentine’s Day

My boyfriend just called me and ask if I had plans for Valentine’s, and I was kinda confused because I would think that he would’ve made plans for us. I told him that I didn’t have any plans yet, and he said great because his dad wants him to drive an hour away to his house so they could spend time together with him and his other siblings. He also mentioned that he was gonna go by himself without me because his dad just want it to be all the siblings, which I kinda find weird especially since his dad could’ve planned this literally on any other day. When he told me this I got so upset and told him that the ideal his dad came up with was dumb especially it being valentine day which he knows 9/10 couples spend that day together, so why would he want to take that away from us, especially when he’s married and should know how special that day is for some of us. Am I being selfish for not wanting him to spend that day with his family? Something also in the back of my mind is telling me what if he’s lying and going somewhere else with someone else 🤔 Ladies how would you feel, and what would you do in this situation?
