Ask exactly as I posted the request,
don't be afraid of the rejection,
in fact.... expect it, expect it 100%,
that way when it happens, you just look at her and smile because she is so predictable.

If she actually agrees (I don't think she will) but if she does, don't jump at it like a love starved pet, just enjoy it the way she enjoyed your massage but again like I said, expect her to reject the idea but don't get mad at the rejection, smile, giggle, but don't get mad.

The lesson being, the one being rejected is usually the person in the relationship doing the pursuing - if you get rejected, guess which one you are ;-)

No more supplicating, wussy type behavior.
Pull back a bit, stop being so attentive, stop being there always, give her the gift of missing you a bit and one last thing:

you making comments about her baking and not wanting to eat her home baked desserts all the time was not why she wanted out of the relationship, it's not even close to being the reason regardless of what she tells you.
