Being a single mother is more than just being alone with your children
Since I've been a mother, I've seen a few times where married mothers will compare themselves to being a single mom. One example was a friend of mine who posted "Now I know what it's like to be a single mom" (because her husband went out with his friends and stayed out until 2:00 am). Another example was a friend who said "Thanks (husband's employer), for making me a married single mom". I've also seen a few posts on CM where the mother is complaining about her husband having to work so much and how she feels like a single mom.
I understand that it must be frustrating to have your spouse/so not around as much as you'd like -- or how upsetting that must feel to have your spouse/so let you down by not being there when you feel they should be. That said - it is still nothing like being a single mom.
Yeah, some husbands may not contribute much at all and might always fall short or disappoint by not helping financially, emotionally, physically -- in which case I can't help but ask "If he is really that bad, why are you with him?"
But - a husband who works hard to provide for his family...or a husband who made a bad decision ONE night by staying out too late? If I were him, I'd be offended to hear my wife say "I'm practically a single mother". It's like saying "he might as well not even be in our lives at all" -- "he makes no positive difference to our family whatsoever"
I just wish these mothers could recognize and appreciate the support and contributions they get from their spouse/SO rather than only focusing on the few negatives. I wish they could understand that being a single mother is about a lot more than simply being the only parent there with the child/ren.
