Dear Marie, my husband and brother did exactly the same , they were loving and caring, then angry and nasty words , the next . I had to walk away in tears many times , but were never nasty to anyone else . I don't think they can help it , it must be chemical changes or medication, or them trying to protect us from the pain of losing them , it must be terrifying for them leaving us , I've only just stopped thinking of those moments, he didn't mean them , he loved us dearly, as did your soulmate, try to remember the loving caring times , people say anc do things they don't mean when they are hurt or scared.  My brother did the same to his wife , and on this site , I've heard it many times , it must be something that happens. It's terrible I know , but take comfort in the fact , he didn't mean any pain or bad feeling, You are alone , but not alone in this.  If you need to talk , scream or rant , do it in here , we are all feeling emotions at different stages , there's always someone to talk to . Please take care .
