Alessandro, you have violated an unwriten, holy and untouchable law here in this forum:
It is ONLY permitted to mention the word "money" (you can say the n-word, hurl insults and freely admit to having multiple STDs - for the femdons here: SEXUALLY transmitted diseases) YES, it's better here to admit to being a sexual pervert than to mention money in connection with women. They will automatically form a "holy alliance" against ALL those who dare mentioning money AND women (alternatively money AND relationships).
If you want living, obvious and blatant evidence for my statement, then look at all the downvotes my comment garners 😀
(The neggers are the ones I mean 😀😉
NOTE do NOT mention money here - not even as a joke! You'll be skinned, burned and buried (exactly in that order)

Now to the serious part:
If something like this happens to you often, repeatedly, then maybe there is something that you do to trigger that kind of behaviour? If you run after people, they'll be likely to think of dispensible. When you corner people, they're likely to break out and leave.
Building a relationship takes time, patience and good will. Did she promise you to delete her account because you asked her to or because she offered it?
(We) Men often think of ourselves to be gentle and harmless, but for a woman requests can easily be read as demands and demands even as threats.
If she's genuinely interested in you, she will call. If not, then what's the point of trying to catch her?
