I think it is daunting to go into a relationship thinking that it should be long term, or you want it to be long term, or anything like that. Of course that is the ultimate goal, but I think its better for me to just take things day by day and not worry so much about finding "the one" that will be with me for life.
I just recently met someone new within the last few weeks and I have already done a lot to run away and push him away. He pretty much told me flat out that he's not going anywhere, as I have touched him in a way that he knows he wants to see this through, no matter what the ultimate outcome. Yes, its scary, but I only try and think about the here and now, so that does a little to ease my anxiety.
It really DOES take someone special who can see through all that you deal with and say "yeah, this person IS worth it!" There are a lot of people in society who just want an easy relationship and they don't really care to be with someone who is a bit more challenging. But you know what? I see it this way.....I don't want to be with people like that because I am an extremely caring person, and when the tables are turned (which they will be at some point in life, guaranteed unless they die early in a freak accident), then they will want/need my support. Is it fair to me to give and not receive? No, I am looking for a balanced relationship, where I can support someone else as much as they can support me, albeit in different ways.
I'm sure some are saying "ahh, shut up Solara, you don't know what you're talking about because you've only known this guy a few weeks" but really, does that matter? He's opened up my eyes to see that YES, I am a great person, a great person who happens to have struggles that lie outside of what is "normal", but that doesn't mean I don't deserve love or happiness. Of course I don't know where this will take me, but I know I need to give it a chance. Maybe we won't end up together, but in life there are no guarantees.
My advice is to listen to those of us here on the forum who tell you that you CAN be in a loving, supportive relationship. Ignore those who don't know crap about PTSD or what we deal with and tell us that we aren't good enough for a relationship. Gee, had one of those people say that to me less than a week ago, funny thing is that she has PTSD, too. (High horses, glass houses, you know the deal, lol)
