I am in a similar situation and I am also a bit afraid. I think it is because it is an unfamiliar situation and we are so used to love being a certain way- and perhaps filled with despair and resentment and pain. It is almost difficult to accept someone who is good for you because then you have something to lose. What if it is a cruel joke and they get taken away? I think it is always hard but with the right person, the way you are, will not scare them away. What's meant to be will be.
I find that with this new love, I do not have to tone myself down out of fear of scaring her away like I have had to in the past with everybody else.
