wanting and not wanting to commit

Well I'll cut to the chase guys.... im 17, kinda like a girl... i think she likes me but i dont know if i can commit to it.. relationships these days seem to never workout and i dont konw if its even worth it... and thinking this way makes me not go for it and makes me stressed out thinking i wont be able to get with her cause my #######5 attitude... well anyways this took about 10 seconds to type and im too tired to proof read it so bare with me, any advice guys? thanks

Hey, DeepThinker! Maybe you can tell this girl that you're scared it may not work out and that you want to take things slowly. I think she might be worried about stuff like this too.
