Ask your inner most soul what exactly do you want to do....
1) Do you wanna cope up with the same life style until she leaves you
2) Being 2 cary can be 2 costly in the end...the more you love..more love turns from sweet to sour...understand what kind of relationship you want.
3) sharing is caring and caring is loving...if all these stuff are absent then leaving is moving
4) Better to get hurt now then 2 years in  the future...if 2 people cannot understand each other..there is no love...it is simply  infatuation hidding behind the shadow.
5) break-up if u are unhappy in a relationship.,...why bear the burden when there are better things to pursue.
6) It seems she might leave you anytime now or in the future...that would hurt more ...so take your action now so there is time to heal the reaction....BE A MAN DO THE RIGHT THING>>LISTEN TO YOUr HEART>>>>
