Help,
The FORMER person they were, and probably still are deep below the awful, festering, bubbling cauldron of the way they present themselves is the key phrase.
It is perfectly ok to love them. In fact, I would think something were wrong if we didn't. All that being said, there is no right or wrong way to handle these feelings. Having these feelings is fact, but the facts may not support these feelings, and that too is ok. I believe in due time these two ideas will be back in equilibrium either with our former spouses or another partner, and definitely within ourselves. The latter is key but all of this is solely my opinion.
Some days are better than others. Hoping this is one of the better days for us all!!
