...being a couple is overrated.
Nahhhhh, it's not. Throwing others under the bus to make one's self feel better about one's lot in life does not suggest one IS actually happy with one's current circumstances.
Congratulations on being a single mom and (feeling like) you're doing it well; no doubt, you are.
"Being a couple" when raising a child is neither over - nor under - rated. It simply is
A situation in which children are reared.
What
should be the goal is to be happy with one's situation and to be handling it well, whether it be as a single mother, a single father, a married couple, an unmarried coupling, and/or a childless
human.
Best of luck to you in your continued success - and happiness - with where YOU are in your life, at any - and all - given moment/s.
