why do they always want Commitment

Commitment should be a four letter word. anyway, i think that my friend's little sister is wanting to jump my bones. she is a nice girl but i couldn't even consider doing something like that with her because i have known her for ever. another friend of mine wants me to get involved with her in a committed relationship. that kind of thing freaks me out. i don't know why.i would like to be able to stand commitment. it is just that as soon as i start to get emotionally close to a female i just shut down. i get freaked out at the thought of what i might be missing by being tied down by one female for the rest of my life. what if i get with one girl who i think is "the one" and i end up missing "the one" and not even know it?
