In my situation, I've made it my own personal choice to live with complete integrity. I would feel 'guiltier' (really more like a hypocrite) if I were in your situation and I did not live with integrity, i.e. gently sharing these thoughts with the other parent and making the honest plans for my family as stated. If you are toying with the idea, you should not toy with anyone else's emotions with the idea. Get solid information and then be honest about the decisions you need to make so your little family can prosper and grow. No guilt there!
