We can only control our actions but not our partners actions...,
Unless she is the one who initiates the problem you can make her perfect, love her for what she is..., concentrate on the positives and everything will be okay...., and if she really loves you she will stand by your side no matter what, therefore the important thing is in getting the right partner because if she is not right she can make your life a living hell...., After all you dont want to be sleeping with your enemy everyday... I have seen a lot of couples wishing death for their partners
