Pay Close Attention To her!When she's "asking questions" she is trying to gain clarity. When she's quite and letting things "slide" she is giving up. And when she's not doing any of the above just know you lost a good woman.
Don't chase someone who won't chase after you. Don't give to someone who doesn't appreciate you. NEVER push a loyal person to the point they no longer care. It takes work to get a person to that point and once there . It's hard to repair the damage
