When you first meet someone , your heart can think of no one else. Then you settle in and deal with daily routines, schedules, and time demands that can slowly tear apart your storybook romance. Tough questions , but then life and romance are filled with decisions and reactions based on feelings. Some will say to keep a spiritual approach, this will ensure everything, others will tell you true love can never die. This is not all you need do.
Romance is like a newly sprouted plant.
It requires nurturing, feeding, and loving care. To much water and it drowns, to little and it withers and dies. The parallel here is that too much or too little of anything needed in a relationship, can and will effect it's survival. Smothering your mate is not good, neither is ignoring them. If you have lost that loving feeling, face them and discuss it.
