I have grown this past year. Changed quite a bit. Fallen in love, and had my heart broken. Rediscovered myself, and in the process found that I am different than I thought I was.
I would expand on this, but I am still figuring it all out.
Relationships are affected by the things we control, as well as by those we have little/no control over (hormones). We have all been there at one time or another, you are not alone. Time and tidal surges of emotionalism sweep our rational minds down pathways we least expect, and often dread.
