Yeah, i think you've answered your own question... if you're this unsure now and feeling sick to the stomach probably means something's wrong. 14 and 19 although 5 years doesn't sound like much, when you're this young you're at totally different points in your life, you've not even finished school, he's able to move out, go to uni, get his own place etc... doesn't sound like the best basis for long term. technically you're still a child, i didn't know what i was doing at 14.. i don't mean to sound patronising but most 19 year old males i know are after one thing...
