Leaving your baby father made things harder or easier for you?

We currently live together and we have a one year old. We both work and we do pretty much everything 50/50 when it comes to parenting - we are alternating night shifts and give each other 3-4 hours of me time every weekend. I am doing like 80% of cleaning and cooking and he is doing 100% of handyman work, cars maintenance and home administrative duties. However, he is overall on the lazier side compared to me - e.g. he needs a nap almost every day, spends a long time on the toilet, gets sick often, constantly complains about being tired or having a headache and that's giving me the ick.

We are having disagreements over raising a child and some other relationship problems but nothing too serious like abuse or cheating.

Now I'm seriously considering separating, getting an apartment nearby our family home and do shared custody. I imagine having the baby every other week, how I'll be able to rest in my weeks off, having my own small space, not having to clean the family home anymore, cook less and do fun girls trips in my weeks off. I imagine life becoming easier and more enjoyable, but I know reality might hit differently. How did switching to shared custody go for you? Did you regret it? Was it worth it having your child grow up in between 2 households?

I'll mention that I won't need any financial help if I move out.
