I 23F am the youngest of my siblings and am expecting my first child. Ive been planning my baby shower since March when the invites were sent out to everyone and we’re having it this month (May). I have a niece and a nephew already (this will be important later) from my brother 27M but my brother 30M has no children. For a bit of backstory my brothers pretty much raised me and were a huge part of my life growing up, me and 27M weren’t very close but me and 30M were almost inseparable. As time has went on naturally we’ve all grown up and we don’t see each other or talk as much but when something big has happened in the past we always get together. My brother 27M of course had his baby shower for his first baby a few years ago and we were all in attendance and celebrated with him. Now the reason I’m posting. My brother 30M informed me that he wasn’t planning on being there for my baby shower. His excuse was car problems, however these aren’t new car problem, they’ve been happening for a good amount of time and I thought giving him a 2-3 month notice would be ample time to get plans in order as I invited other people from the area he currently lives (about 2 hours away). But that’s not all. Before he told me he wouldn’t be coming he also let me know he has plans the week after my party to take his friends young son to a convention and he absolutely could not miss it because he promised he’d take him. I think that’s the part that hurts the most knowing he’s going out of his way for someone that’s not related for something that happens at least twice a year but he couldn't find a way to be there for me. Maybe my hormones are making me overreact but this has been eating me up inside and I want to go low contact with him so I don’t have to hear about how he's prioritizing other peoples kids. So WIBTA?
