She is letting you know that her relationship with her son is more important than her relationship with you..
You wording is a tad confusing. But if I understand correctly, I have (successfully) made it point to make the phone number less conspicuous by simply asking a women "may I call you?" or "can I call you?". The number is then coincidental to the real objective. Getting the number is not the objective and to me sounds mechanical and classless..
nice body ^^.
I would choose to walk away from this situation..
This is where I don't want to put the three month effort into anyone, if I already know there's a big, red flag. Experience has taught me not to ignore these flags..
As for this "crush", you either cut all ties with her, and work on your marraige, or you get an anlulment from your wife and go be with this woman. You said you have had past crushes, was this while you and your wife were dating?.
