YOu certainly have had the trust in your relationship betrayed. Love and trust are two different components of a relationship. Love bounces and yet trust shatters.
SOme men do that and it can really mess up the dynamics of a relationship.
When we are feeling sorry for ourselves, we just want others to feel badly and we want to focus on how bad and wrong the other person is. Remember your worth and your value and get creative. Begin crafting a plan for helping you get what you want. Get as clear about that as you can. You have been through alot.
