Hi Matt24,
Welcome to the forum. :)
Relationships are very difficult for me too and I know that PTSD plays a huge part in that, so I can definitely relate to the catch-22 frustration/depression. Being disabled by PTSD, I spend a lot of my time alone, bored, and depressed.
Ya know, I think relationships are hard for most people, but especially for us. A lot of times, our trust has been betrayed.
Over the years I have learned that it takes two healthy people to have a good relationship and not everyone is dedicated to self-improvement the way survivors are, ....so I guess I am saying , don't be too quick to blame yourself or the PTSD for relationship problems because everyone has them and both people involved are responsible for the relationship, not just the one with PTSD.
Hopefully you will find someone intelligent enough to appreciate you as you are, regardless of any PTSD challenges that you may have as a result of being traumatized!!!
wishing you peace,
LH
