Life comes to pass in that you and he may need to "rethink". Just RETHINK and while your at it LISTEN to why you came together and began to build this relationship plus a family. No need to regret now, that's past. No need to fret now, that's just fearing the future. If you can find a piece of forgiveness within your heart for this one person (that you feel may not deserve it) that would be the best thing you can do for yourself and him. The direction in where your relationship was being led to is now changed forever. Learning to forgive and doing it over and over again changes everything in your destiny because you listened.
When you learn to listen to your intuition or some may call it "spirit guides or angels" you become the one who removes your own blockages from your life, from your destiny. That doesn't mean you purposely change your destiny, but you have removed or somehow avoided the tiny distractions from it by listening. That's the main point. It takes listening to your intuition that will forever change the direction you make in any situation, especially one involving a relationship.
"If each person can forgive another and their actions, the world will begin to move forward in new humility and in higher humanity."
