She seems really mature, has a career, her own place and all the other shyt we want in an independent women.
Most SMs are like this. They're forced to grow up because they've started a family and need to take care of it. They need to learn to support themselves, learn how to cook, clean, and keep the bills paid.
There's always the dark side of SMs. They have baggage, and it's not just the child. They're going to have issues with the child's father whether he's in the child's life or not. She's likely to have lower self-esteem for the sole fact that she's a SM and is somewhat undesireable.
Unless you're a single parent yourself, I would highly suggest not getting involved with a woman with kids. Why waste your time on a family that isn't yours, and can never be yours? Why finish a project that someone else started? You're better off keeping to women who are childless if you're even remotely thinking about finding a good woman to have a LTR with.
I'm 26 and I've been 'seeing' this beautiful 21 yr old woman and things are going really great, but she wants to get "serious."
When you get "serious" with a SM, you're expected to take on some responsibility with the child. Trips to the fvcking zoo, amusement parks, and other things. You're going to be sucked into parental work whether you like it or not.
When I was in the dating scene, I wrote off LOTS of SMs. The main qualifications for me dating a SM is that she had to be hot (9.5 or higher), and it had to be for sex only. But I could never see myself adopting someone else's kids. If I were to have a family, I wanted to start fresh.
She is 21 with a 2 y.o. son, meaning she was knocked up at 19 and fresh out of high school. Avoid this woman like the plague.
I'd like to expand on what Rollo said. Most women in their early 20s have yet to go out and "live life". This woman is missing out on this point in her life, and she's going to feel it when she hits her 30s. Women need to have that feeling of accomplishment before they hit their 30s. If you find a woman who says "I had my fun, accomplished what I wanted, and now I'm ready to settle down", you can guarantee that she's ready to settle down comfortably into a LTR. A woman who is 21 is going to feel that need to "live life" sooner or later regardless of whether she's a SM or not. Most women under 25 aren't ready for a LTR because they're still "living their life" or have yet to do so.
