I recently (28f) paid to go on a holiday with my parents. From the start, my dad (62M) was grumpy… this involved: shouting at my mum in the car; being was put downy to me when I asked him he was okay (uno reversed it back around onto me) making me feel bad for asking; and, generally bringing the mood down. One other thing to note is that my dad’s mum has recently gotten very ill (cancer, for which, she will likely refuse treatment, which is fair dos to her) and that will have been something on his mind at the time. He took this grumpiness out on both me and my mum multiple times. After another aggressive blow out on his side, I ended up having an outburst on mine. My emotional outburst comprised of slightly raising my voice, asking him to take a breath (probably speaking to myself also), that I’d had enough of him taking out his shit on us and that it wasn’t fair. Followed by a little bit of crying. He seemed shocked and didn’t say much after this. Later, I was having a little giggle with my sister in the back of the car as to how I let my emotions get to me. My mum reassured me that it was okay/understandable. (She had previously tried to have words with dad privately about this grumpiness and that it wasn’t okay). She also asked him if he was going to apologise, to which he said, “Sorry for being me.” This has since stuck with me. The rest of the holiday after that, I just stopped bothering to communicate as much and kept my distance (focussed on my sister instead). My dad did try to reach out to me in his own way - trying more to communicate with me and be close to me but I had already shut down. I know overall that this is a very minor thing to have to deal with but I can’t help but just feel like he can do one. But equally I feel guilty for not being warmer to my dad after his repair attempts (though not verbally communicated). AITA ?
