And It Still Scares Me!

I've been with my boyfriend for a long while now, and i still really panic that we're too close! He understands me more than anyone in this world, and i'm quite a hard faced person, and i generally cut emotions out of situations so I can deal with the **** in my life. But he knows me for who i am behind it all and that's really scary! I know it's going to hurt if it ever ends. And I'm so scared of being hurt...
... But I love him, and i'm not going to live my life waiting to be hurt. I wouldn't be the person i am today without him and it's not worth throwing away over doubt. it's ok saying that on here... now i've got to believe it.
