Don't go out with him if you don't like him.
One of the most awkward and uncomfortable things to do is turn down someone who is really into you, when you're just not into them. It's not easy to find a way to turn him down gently without bruising his ego. Think about how you would want someone to break up with you. You would want that person to be respectful, honest and straightforward, so you need to do the same.
Instructions
1. Pull him to the side privately. It's embarrassing enough for you to have to tell him that his interest in you is not reciprocated, so don't make it worse by doing it in front of his friends or within earshot of other people.
2. Compliment him while letting him down. Start the conversation off by telling him that you think he's got a great sense of humor or style or is really sweet, "but..."
3. Be straightforward and honest about how you feel. Don't beat around the bush or confuse him by saying, "I'm not sure about us" or "maybe we should just be friends." This leaves the door open and could give him hope.
4. Explain why you don't want to date him. Be honest about why you don't like him. This will help him move forward. If you don't think that you have anything in common, tell him so. If you're interested in someone else, be honest about it.
5. Don't linger. After telling him, excuse yourself politely so that he can pick up his bruised ego with dignity.
6. Don't get back in contact with him. Don't text him asking if he's OK, or saying you want to hang out as friends. If you do want to be his friend, give him ample time to get over you. Otherwise, you will just confuse him.
