Relationships change over time sometimes for the better and sometimes for the worse. People change over time, some get more set in there ways ,some open up more. None of its right or wrong.. When communication stops, one or both aren't getting what they need or want from the relationship and resentment builds..

This is where the problems begin. All relationship require compromises. Everyone thinks our partners should just "know" what we need or want, No one is a mind reader. That would be like walking into a restaurant and assuming the waitress knows what you want to have without you "asking" for what you "want/need"

Relationships are always in need of tending, Kinda like a Garden it takes work to keep everything growing.

Just my thoughts
