AIO to being left out on a family holiday (vacation)
So I'm a guy living in the UK. My family consists of my mum and two sisters (one lives here in the UK with us, and the other lives in Sweden). My dad passed away Christmas day the year before last, which means I am the only direct male left in my immediate family. I do have 2 brothers-in-law, I love them but I don't feel as close to them as I do to my direct blood relatives.
Today, I suddenly received a WhatsApp message on the family group chat with a photo of my mum and sisters at the airport. That was how I found out they were all flying to Denmark together. Because my sister lives in Sweden and the rest of us are in the UK, Denmark was clearly chosen as a middle-ground for a family reunion. This means they had to have been planning dates, booking flights, and coordinating this international trip for weeks or months, all completely behind my back. I was never invited, and no one even gave me a heads-up that this was happening and I'd love to go to Denmark.
When I asked what was going on my sister replied with "girls' trip to Copenhagen." To me it feels like a convenient excuse to exclude me maybe not intentionally. But regardless, even if that was their true intention, finding out via an airport selfie on the day of departure feels incredibly secretive. What else hurts me is that we haven't been on a family holiday since we all lost my dad. My mum and dad said they would visit me and see my new place but my dad got sick and obviously priorities changed, and he never did. Then my mum said she would come and see me, also my sister in the UK after my dad died said she would come see my place with the kids. I've gone and visited them but they've never reciprocated
Am I overreacting for feeling completely left out, neglected, and deeply hurt by this. Especially being the only male left in the direct family, I just feel a bit singled out?
