Single mothers. Not till you pushing 40.....and even then..
This why you settle down in your 20s
Truth.
NGL, I messed around with quite a few single mothers in my single days. Made it work by:
Only went for ladies aged 40+ (I was in my 20s) with kids that were close to middle school age and older.
Why? Because young single moms are stressed the fukk out. They're juggling work, raising a small child and then likely having complex feelings about Mr. Baby Daddy. The average woman doesn't get pregnant with the expectation that her and Mr. BD will split. They may not marry but she's expecting a situationship with co-parenting and MAYBE a chance at a long-term dating/cohabitation thing.
The 40+ ladies...usually Mr. Older Baby Daddy has already found another woman, maybe even married her. Single Mom and Mr. Old BD have spent all their lust coins and either tolerate each other for parenting or have no communication.
The kid angle is important as well. A 14-year old kid has a much higher degree of autonomy compared to a 4-year old. Mom doesn't need you to be the kid's father. She's looking at you more as a potential fukk buddy and partner...rather than a father/paycheck. Women with young kids are too emotionally vulnerable and you're not winning against her Baby Daddy. Mr. BD is who her primal sexual instincts told her to pursue. Mr. Wannabe Step Daddy is just the provider/moneybags guy...and the minute she gets a whiff of Mr. BD's pheromones, she's spreading the legs
