Re: Done everything right so far. Please help me so I don't mess it up!
You obviously have some background knowledge on the game which is a good stepping point. Here are all the good points I picked up on:
1) Platonic friend zoned. No one likes to be friend zoned, and by doing that to her, you have created fear of loss. Good going!
2) Cheeky text at the end. Good. You realised that this was an opportunity and took it. Now you have given a glimpse of the relationship in terms of the fun times you must have had.
3) Not saying anything when she talks about women in your life. That is superb, also the fact that she isn't dating anyone.
4) Even though you must miss her and want to be with her, it doesn't seem fully apparent you do in the text above. Meaning, you have a good amount of control within yourself to not let it be too apparent. Which is a great thing. Just watch out, because if she does find another guy - most likely a fling - then you may feel extremely down. Just be prepared in case things go tits up.
Those things on top of the fact she is asking you about other women is a huge bonus. I think your right on your way to getting her back as long as you carry on the platonic vibe and building up that cheeky cocky behaviour very slowly.
Also buddy, don't say you might have got another girl pregnant. That would only show how irresponsible you are to get another girl pregnant. But you can hint you are seeing other people. For example, if she texts or calls you, just say "I have to go now, I'm meeting someone in 5 minutes". Even if your not, but hey if you are then fucking ace!
P.s. Keep it going man, you seem close
