Things will kill your relationship: insecurity, trust issues, jealousy, lack of communication & assumptions. I just witnessed this in my life. It only took 5 months.the shortest relationship I've ever had.
Until God opens the next door, praise him in the hallway. I think this quote is just a cliche and doesn't mean much to anyone until they find themselves in a hallway and see how difficult it can be to trust and praise God in times of waiting.
Listen to your own voice, your own soul. If it doesn't feel right it probably isn't. goes to the last lecture life teaching: live your life the right way [as you perceive it to be] and let God and Karma take care of the rest.
