Love is not the greatest glue between two people trust is.

It's really very simple....
If he doesn't follow through with the 'little stuff' how can you trust him with the big stuff (like your body, soul, spirit.)

Does he show up on time?
Does he take you out when he says he will?
Does he keep his promises?
Is there always an excuse or does he own his mistakes?
Can you have an argument without shouting, rage or him leaving (physically as well as emotionally)

Don't settle, choose a man you can trust with the little things, the big things and all the things in between.
