I think if there is commitment from both, then the relatioship
is possible. Communication will allow for intimacy. As all human
are different, there is bound to be conflicts in relationships, the
important thing is how to sort out the differences in a
constructive way through communication. As long as the both of them
are willing to commit, communicate and resolve conflicts, they will
become the perfect match after all these work, even more perfect
than the more ideal partner.
If she just think that the other is more ideal and goes for him, i
think that she will fail again as there seems to be the lack of
commitment and communication.
So i think that the guy should have a good talk to the girl and see
what she thinks.
