Hobby Ideas

My husband and I have recently decided to take a break. We both need to work on our own mental health, and have been toxic to each other recently. We decided to take some time apart. Both knowing that we may not get back together if we find we prefer being alone. However, we both still currently do want to get back together inthe future. We are still living together because we have a 1 year old son and another on the way. However we're working separate shifts and minimalizimg our amount of time we spend 1 on 1. So, in meantime, I need to find a hobby besides being a wife and a mom. Does any one have any ideas or suggestions?
