G.M.
From reading your past posts I see that your ex had some issues. This would definately make you take pause at attempting another relationship for sure.
Ask yourself again if you really do want another man around the house to worry about? As far as putting yourself out there purposely looking for a soulmate, I don't really think that is the right way to go about it. Somehow, when the time is right, love finds you without you having to put much effort into searching for it.
You have your hands full with a child and a job. If you concentrate on you and your child, you will find yourself in places where occasional conversations with men are bound to happen. Maybe at the park or the zoo. Don't ever openly date in front your child at this point. Exposing children to boyfriends can get confusing for the child, especially if they become "attached".
Do some chatting on eharmony, and if you feel comfortable enough after some lengthy e chats and phone chats, meet a guy for lunch.
Don't sabatage a new relationship by "wanting to be the boss" otherwise you will end up with a baby-man that will get boring real fast. You sound like you want an independent man... they are out there I'm sure.
I dated my current (2nd) husband for 10 years before I decided to tie the knot for good. There is nothing wrong with extra long engagements, they usually lead to extra long marriages. I dated my current husband for an entire year before we had sex too.... and he really loved that about me and still brags about it to this day. It was his second marriage too and playing the virgin game was very fun for both of us.
