Infedility... its the reality. Familirialty breeds contempt.. you said your already in 10 years? That made your husband very comfortable, may i say lack of spice or something new in your relationship.

You may thought love hurts. No Pride hurts. It must be your pride that left you hurt, because you are not reeady to accept the fact that he cheated on you. Love is a wonderful thing and thats what you had for those 10 years.

If you cant forgive him and would like to see your life in the next future without him (which you may not yet see now coz ur blinded by the pain) move on, get a new life. Create the life you want.

But one thing is for sure, it can happen again or not in your next relationship but just remember that whatever happens, trust in the Lord with all your heart and lean not on your own understanding.

This situation might want to teach you something, a lesson perhaps about acceptance, forgiveness, humility and true love.
