Is your wife going through menopause or has already. If I can live with my spouse in the basement for over 11yrs with 3 mature children still at home & survive, these days it makes sense with the new COVID rules. The government was saying that if you don’t have a legal suite in your house for both of you to reside together separately that you are still considered common law. Not anymore though I recently found out. As long as there is a judge’s order of financial separation and children placements you can still live together but claim separate for CRA. It’s been quite the process. Once that’s in place then you should be able to try to COVID date & see if any jealousy surfaces. Maybe she needs to see you can move forward.
