Sad because of Partner?

I recently started a poll here in which 114 people voted and after lack of good work/salary.... Absence of good partner is the most picked reason for their sadness.

If I assume you have a partner but he/she is not good.

What qualities of your partner make you feel sad?

PS: I'm gonna get married in coming 2-3 years. That's why just started asking such questions quite recently on this platform.
