Hey Combat
So it would seem that you're on your own Combat. One thing you can never have any control over is how someone will react and what they'll do. No matter what you may want in this situation you may have to just put a period at the end of it and try to move forward on your own.
For what it's worth, it's time to make a good plan for yourself. Married or not we're always on our own with this thing. It's a very rare person, either spouse or girl/boyfriend that will take the time and make the effort required to try to understand the problems of being with someone with PTSD.
From what you've said it sounds like the two of you aren't in synch like a couple should be if there's any hope of a long term committed relationship. It's both sad and hard and my thoughts go out to ya' Bro. Hard as it may seem now, you'll move on from this. People with PTSD are survivors, it's probably the thing we learn to do best. Don't know if that's a good of bad thing but it's how I see us.
Take some time for yourself. If you can go visit friends a few states away or just do something like take a trip somewhere that you've never been. Something to change both the landscape around you and of the mind as well. Time heals all wounds, or some of them at least.
