Why after 17 years

She's lost that feelin for me, told everyone I was mean, leaving me with 3 mouths to feed. Whats wrong with her today, why don't the kids want time with me today. 3 years gone, I'm still not me, working for a living, barely getting by but, my kids love me. I refuse to give in. Yet, you still call me "Dear, hun" why do us so dirty?
