Myaleah, I am Kathy's daughter, I'm 24 and I have PTSD. I've been reading yours and some other's threads in here and I wanted to comment. As everyone has said there's no way to know if your boyfriend has PTSD or not unless he gets evaluated and gets a diagnosis. But I do know, if he does have PTSD and is obviously not in treatment yet, any kind of relationship you have with him is going to be very up and down, and very difficult for you. I know because before I started working on my issues, I had a hard time being with anyone, family or friends. I avoided my family a lot. I could only stand so much attention, even if it was positive attention. Even now I have trouble if friends email me too much even, or if my family talks to me too much, and so on. Sometimes I am just so stressed and tired and I need to be alone. If people bother me when I'm in that state, I get really agitated and try to avoid them even more. I've actually stopped being friends with people before, when they've pushed me too hard, asked me too many questions, wanted to talk too often and so on. I've blocked tons of people from MSN, facebook, etc... because I just couldn't stand them contacting me all the time. I stopped being friends with lots of people without any explanation, even good friends, and ended up really hurting them.
I'm not saying what I did was right, but at the time, my PTSD was unmanaged and honestly, all I could think of was, what can I do that causes me the least amount of pain? Because PTSD is really painful. You're in a constant state of stress. Anything you can do to lessen the stress, you will do, even if that means avoiding people who care. It sounds selfish maybe, but think about times when you've been really sick. Do you want another people around you, or do you want to be left alone? PTSD is a sickness, and sometimes you feel worse than other times.
If your boyfriend does have PTSD, it's up to him to get the help he needs. You can be there for him but he has to do the work. He will get better if he works on himself but it's long process. Anyways I just wanted to share that with you, I know we aren't easy people to get along with. Hope things get better for you and your boyfriend.
