My fiance of 6 months is an Iraqi vet. 100% disabled ptsd. We are so similar and get along amazingly. Not a day goes by we don't make each other happy at least once but sometimes we go through periods where he gets so angry with me about everything and distant and mean and basically one foot out of the door. Then we fight and break up for a couple of hours then we are fine again. He doesn't take his medication and I didn't think he needed it but ten days ago he wrote a Facebook speech about how I was the love of his life and how we were so good together. Then two days later hecalls off tthe wedding. Now he wants to but he won't barely speak to me... He's stopped hugging me but still laughs and jokes and smiles then goes cold again. I don't know if he just doesn't love me or if this is ptsd. But the emotional whiplash is tearing me apart. I am in constant terror of the next time he is going to decide he is fed up of us. What can I do?
