I could really use some advice.

So I was sexually harassed for two years, my freshman and sophomore year of high school. (I'm a senior now) When it was finally stopped I was so relieved, I could finally get on with my life. I met this really sweet guy and we started talking. I had met him through a mutual friend and we became pretty close. He knows about everything that happened and he helped me get back on my feet.

The other day we were hanging out alone and he tried to kiss me. I panicked and made things awkward. He apologized and was really nice about the whole thing but I still feel terrible.

How do I work to get over the fear of being too close to someone? I'm so scared of letting myself be vulnerable and getting hurt again. Any advice?
