I too get freaked out about the possibility of letting another sentient human being get that close to me, especially one who has been alive 28, 29, 30 years - who has the level of maturity that I'd want in a partner. Its not to say that nervousness over that is enough to prevent me from going forward, just that I understand that from time to time it would likely flash across my eyes and be apparent to the other person. Some people can roll that off, some find that unforgivable, I'd like to think that I have enough going for myself and can find someone who's life has been pointed in the right directions to where the things that I go through or have been through won't be a point of friction in the relationship. Its not that I even relive the bad times daily, but, once people get past my facade - that I went through them I think can be seen in my day to day thoughts and decision making, in small ways but ways that definitely would register for those who pride themselves on reading into people.
