Why single mom?

Everywhere I go people are always bragging about how great single moms are what is so great about it? I’m a married mom and I get no appreciation and recognition. Also I feel like as a married women I’m not ever able to complain about anything because why you have a husband. Single mom are able to do it and people feel sorry for you. I’m not trying to bash anyone I just really want to know what is so great about being a single mom?
