Too many to be listed in general... But for her case, it would
be TRUST ISSUES, SERIOUS lack of FOUNDATION, and strong
INCOMPATIBILITY...
And it's absurb to be talking about marriage at this point when
they have not even been dating over quite an amount of time...? It
also seems that this guy is much more interested in the idea of
'marriage' alone than showing much of any other interest in solving
the problems on hand... So what makes you think that he would even
be doing something about the problems after the marriage?
Marriage is no joking matter you know...? You seriously think she
should be taking that kinda chance with this 'gamble'?
