Well, I call that kind of situation like her's "dealing with your addiction"

Sometimes when you enjoy something too much you try to avoid it not to get dragged into the level where it will start causing you problems. So you just go no contact or even get offensive to avoid temptation.
She really liked you but since you were obviously the wrong choice, she left you.

Now, you are acting like a drug dealer offering recovering addict a free dose of crack.

I don't really know what to recommend to you as it is even not clear what kind of relationship with her you want, but I think it is a very bad idea to hurt people who love you. You can use and exploit them moderately but you have to think about their wellbeing.

If she does not talk with you at all, there is nothing much you can do unless you somehow engineer a situation where she will be forced to interact.
If you still can communicate at this time you should just tell her straight what do you want (just don't use blunt words) maybe even explain what you were doing with her all this time (because she really really wants to know that and it would give her relief) then negotiate some compromise if you still have some common interest at this time. If she has no other options she will agree.

If it does not work, not a big deal, as otherwise even if you get her back it will be too much stress to lie all the time.
If you succeed you actually get an ideal relationship.

In fact, it is not even clear who was the bad guy in this situation because she also could have been just trying to hook you and turn you into a sucker provider for her child. This is the goal No.1 for most single mothers.
You may believe that she was your plaything but in reality, you could be her prey too. Single mothers are just as easy to get as it is easy to catch a cat if you are mice. LOL
They will show extraordinary sexual performance and ideal character just to get you hooked on them until you agree to marry and then it is the last time you had sex with her.
Although sometimes, even a cat can fall in love with mice :)
