OP, your posts definitely come off as a selfish dad unwilling to step up and do his part.
RE: Divorce. My earlier post was tongue in cheek. However, my ex an I did have some tension in our relationship from this and we did talk about it with a marriage counselor. It came from the extremes. Her view felt like she wanted 100% of my free (not-scheduled) time to be 'family' time. This meant scheduling things like basic chores... mow the lawn, etc. And when those chores were finished and I wanted to just relax for a second - no deal, time to do family time. I really valued my free time prior to my son coming along and to her it probably felt like I didn't want to be present as a father because I was still fixated on other BS. The reality was somewhere in the middle for both of us.
Anyway, her view didn't align with how I saw parenthood. I am totally ok with dad/son time, mom/son time, and family time, but it felt really hard to make that happen in our relationship. It was definitely a communication issue. As others here have said, work on your communication. We were able to work on this to some extent. I had to make concessions, or schedule in hobby time.
We are now divorced, but our relationship is better. Not to go down that rabbit hole, but it doesn't have to be a negative thing. There were other, bigger factors leading to the divorce, but one of the biggest things that came of it was regaining some of my personal time. We have 50/50 custody. I value the days my son is with me and its 95% dad/son time, and 5% get out of my hair so I can get a few chores done time. The days when he isn't here I can do as I want. That was a HUGE weight off my shoulders. I still don't participate in hobbies at near the level I did pre-marriage, but its nice to have the option. Honestly right now the biggest thing keeping me from participating in most hobbies is home ownership, not parenting.
All kids are demanding of attention at a young age, and giving them attention doesn't mean you are a pushover. Its part of parenting.
What do you want? To spend less time with the kid? To get E36 M3 done? Figure it out and have an honest discussion with your wife about it, but don't expect things to go back to normal. Consider for the sake of your sanity/blood pressure/marriage putting of some of the things you have to do, paying someone to do them, or just moving the berkeley out of the house (since it is a constant source of stress for you) and living in an apt. until the kid is older. Now isn't the time to be trying to do all this yourself.
