I don't know your age, but it's clear from the words you use that you are someone who doesn't like to hurt anyone's feelings, and it's also normal to have some insecurity that since you said you liked him, his request that you two be (I assume by girlfriend, that means exclusive) a couple and not see other people may have raised some fears that if you said no, even though you weren't sure whether you wanted to be exclusive, you may lose him by not agreeing to his request, (or, as I said, hurt his feelings by being honest). Your word "confrontation" is a little troubling, and I wonder, has he done or said anything that hurt you physically or verbally? I hope that is not the case, but again, that word concerns me, since an open discussion in which you are honest with someone with whom you have a romantic relationship should not be confrontational in this case, if he really cares for you as you suggested, and you are just afraid because you don't want to hurt him, that is one thing, and you just need to be honest with him about how you feel (or that you like him a lot, but you realized after you said yes that you may have reacted because you like him and said yes rather than letting logic dictate, which would require that for both your sakes, you should take more time to get to know one another before making that commitment). In any event, if there is any fear on your part of this person, no matter how great they are most of the time, because of any behavior that scares you or hurts you, you need to take care of yourself and seek help immediately from a professional who can guide you through this, but do not stay in a dangerous situation please, they do not change, and if it is not the case and you just need more time, it won't be a problem to him and in fact he should appreciate your honesty. If he doesn't, and reacts badly, how much does that say about him anyway?
