confused and need some advice

I had dated someone for a while who is in the marines and he returned from Iraq for the second time. I did not know him before he went to war so I can't say how different he was before he went over there. At first things were going well almost too perfect, then one day he just stopped talking to me and I havent heard from him since. Throughout the time we knew each other he told me about his nightmares he was having and other normal ptsd symptoms that he had it even took him an hour to say I love you and he cried the entire time. Normally I would just think that he found someone elsebut we had talked about marriage and he expressed his love for me I know that he actually did care for me. Is this normal for people with ptsd to do? Should I just wait for him to come back some day ? I'm not sure he even will I just want to know if this is a normal symptom for someone who is going through ptsd.

Hi keg, My story is that I married a great guy who was a police officer. Shortly after our marriage he transferred to personal crimes, then homicide. There were riots in our city and since his transfer 3 fellow police officers who he considered friends were killed. Since he was on homicide, he was put in the position of having to put one of his friends into a body bag, then made to direct traffic for this man's funeral a few days later.......That was seven years ago, I am still looking for the support that I need. My husband came by his demons honestly, and my heart breaks for what he has endured, but, I and our children, especially our oldest boy suffer also. There are countless days that we walk on eggshells, and tiptoe around his moods. I know now not to take it personally, but you can't go about life as usual with this kind of disorder. I will stand by my husband because we are married and I made a commitment, however, if I knew then what I know now, I'd have made a different life for myself. If you continue this relationship, you are asking for a lot of heartache, please don't be the martyr. You have one life, one chance. To be supportive is honorable and loving yes, but in my experience PTSD doesn't go away. God bless you and guide you in your decision, I know my response will anger some people, but sugarcoating the truth isn't my way.
