I'm currently dating a single mum and have been for close on 3 years.
My experience has been good but I definitely think it's an exceptional situation.
She runs her own sucessful hairdressing business, very independent, from a good family and has huge respect for her father. No sh1t tests and no attempts to rattle my frame.
We've spoken a lot about male and female roles and we're on the same page about who should lead and who should support.
In her work she deals daily with women who blurt out all their problems and she's heard plenty of stories of women fvcking over good men.
The kid factor has taken a bit of time to work out, some may view it as negative as they take up a lot of her time, I view it as a positive because I like some space.
I have a son, she has a son and daughter, they all get on great, it's a positive for my son as the experience of having siblings is teaching him valuable lessons in dealing with others.
It's also a good thing for all of them to see a healthy adult relationship.
I wouldn't even consider dating a single mum if you don't have kids of your own though, for me it's taken a long time to feel a bond with hers and this would have been near impossible if I wasn't a parent already.
