Hi Saec, I get what you are saying completely. I understand your need to communicate with him, to let him know what you are thinking, to feel wanted in his life. I understand when you say that your rational self knows that you should give him space and leave him alone but your emotional self leads you to behave in what seems like an irrational manner. When you commit yourself to a relationship and everything is going great, then suddenly everything is turned upside down, it is natural to want answers and feel like your feelings should be equally important.
After 28 years together, PTSD has finally won, my husband isolated from me completely. When I pushed for answers all I got was 'I don't love you anymore, I'm not sure when I stopped loving you'. They were the most painful words I had ever heard. I had devoted my life to this man, gave up so much for him and his military career. I felt used and like all those years were a lie. I left him 4 months ago. For the first month I was in touch constantly and all it gave me was more pain.
It was after I left him that I found the forum and learned a lot about PTSD. I learned that maybe he doesn't mean all that he said. Maybe one day he will have answers. He needed space but didn't know how to ask for it. I took it all personally and I am still coming terms with it all. Don't beat yourself up about what you have done by texting constantly. You can't go back and change it, you can only start changing things from now. The hardest thing I have had to accept is that I can't help him and he sure doesn't want me to right now. I have slowly learned to back off and leave him be. It isn't easy and I am in a lot of emotional pain but I am not adding to his problems anymore.
Try to be strong, find something positive to fill your time, take one day at a time. Try writing down in a book what you would like to text him and why, but don't text it to him. I found this helped me a lot. Being involved with a sufferer often feels like a onesided deal and it is unfair, but I guess it is also unfair that they have endured a trauma to get them to where they are.
