This argument would've not even been a thing if he was out. But because you can't see him, hold him, talk to him and your time is very limited this interruption seemed much bigger than it actually was. Its the circumstances that are causing the rift. Circumstances you didn't ask for but have to deal with none the less. The amount of stress and anxiety of having a loved one locked up is not something you can empathize with unless you've been through it. Try to be kinder with one another. Because if you can't rely on each other for kindness rn then what even is the point.
