If she does dump her fiance for you mia,who's to say won't do the same to you later?If she ends up
willing to do it to him,she may do the same to you.
One of my girlfriends was dating a guy when we met. She broke up with him because of me.
(Of course, they were not engaged or anything...)
That was 16 years ago, and we are still together today, been married for 11 years.
Nothing is certain in life.
