Opinions on parenting

I may spark up a debate about this but I’m curious to find out. At the beginning of parenting with my partner things was amazing my partner couldn’t do more for me… when I was breastfeeding he made sure I was fed and I had a drink at all times… when he eventually went back to work he would come in go for a shower and quickly rush to look after the baby while I went for a bath/ had some me time. This lasted for about two months. My son is now five months and I’m finding I’m doing things a lot on my own or I get help when I ask for it. I understand my partner works and is tired but so am I and I just need some time for myself. The only time things will be done around the house or helping with my son is when I ask for the help and by that time I might as well have done it all by myself. I just wish he’d use his own initiative to help me because I get so mad having to ask all the time and he should know when his son had a feed last (esp when he was the last person to feed him) or know when it’s time to start the bedtime routine. Am I wrong for getting so mad at him… has anyone or is anyone else going through this and how are you coping because I’m furious 24/7 and currently hiding in the bathroom so I can write and rant about this otherwise I’d be doing everything again.
