I can relate to how you feel about being disposible. I have felt like that also. It just seems so easy for these guys to dump us and move on.
In reality it is not. They just make it appear this way. They are so messed up. We don't see them when they feel guilty, ashamed or embarrassed about their behaviors. They have these moments, they may be quite fleeting though.
Your inlaws make me angry. They remind of mine. They have no idea of what you have been through, seen, heard and experienced. They will never know even if you tried to explain it to them. Let them go for now too. They will soon learn the truth. You in the end will come out the winner.
