When you are leaving the old cycle of intensed emotional attachment, you go through the process of awakening, and naturally your level of empathy may decrease because you're thinking more logically now.

One important thing that we can take note of is that we are dealing with humans that has emotional needs and very little logical needs. You have an amazing woman in your life who is willing to stick with you, you have to compliment or say things which shows that you care.

This is called communication. There is a show and tell aspects to it. It is detrimental to assume someone will always stay by your side. Communication with them can be in a form of compliment (direct/agreement)or taking up responsibilities(indirect) that will offer them assurance that you are indeed worth their emotional investment.

Add-on: Someone once reminded me, "You have to sacrifice some inner-peace of mind, to find a genuine a relationship"
