> Solitude in your 30s (particularly as a DINK or SINK household) is dangerously addictive.

Can confirm (SINK).

The real problem is that solitude in your 30s is peaceful. So peaceful. So much so that if you built your own safety net and covered your back, solitude is so peaceful that you might end up not even wanting a romantic partner at all.

Anybody that had their fair share of storms in life can confirm that having a calm, peaceful life of solitude can be so peaceful one often doesn't really want to change that.
