I've been seeing this guy for a little over a month and everything seems to be fine, but I have this horrible feeling.

I feel like he's going to wake up one day soon and no longer be interested. I've had people I was seeing say "meh, not worth it" and skip out, completely out of the blue, many times before. I seem to have internalized that. It's been a while since I've let myself grow attached to somebody, and I'm fighting it pretty hard here, but I don't even know why I'm fighting. I like this guy, and I'm pretty sure he likes me. I should let myself like him back. It's not like I'm planning a future with him, I just want to feel comfortable with another person for a while. I just want to be on the same wavelength as another person for a few days at a time.

I get this problem every time I start to like a new person I'm seeing, and I have trouble putting everything into perspective. I don't want to feel like this person I don't know very well yet is capable of breaking my heart. That's a scary prospect. How do I deal with this? Anyone out there have the same kind of problem? Commiserate with me!
