Instead of asking us, you should seriously ask youself, "Do you
want this girl to be your girfriend?"
You can tolerate her personality, for the time being (because
the relationship is still new), but later, believe me, your
resentment will get the better of you, if you do nothing. If you
try to control that girl, she will resent you. Don't
expect her to change. It is you who should make a
wise decision.
There are many girls out there, find one that suits you
naturaly, so that no modifications would be necessary.
How do you choose your clothes? Pick anything, and then alter it
to suit you, or do you choose the ones that fit you? You
should give more care in selecting a companion.
She can be your friend, you can be her friend, nothing
more, just like her ex.
