So I've been having a hard time with regret this week and it's all because of what I did to this one guy. So the other day this guy I've known since late August told me he wanted to date me. At first I had mixed feelings, but overall I was happy, because he seems like a good guy. However, a part of my mind decided to ruin things.

On Sunday I went out with him intending on explaining my feelings of hesitation, but otherwise agreeing to date him, but when it came down to it I couldn't stop myself from saying that I didn't want to date him or anyone else, ever, and that I preferred to be alone for the remainder of my life (I'm only 21). It was a complete lie, but I just couldn't stop, now I am suffering from regret of just throwing away a wonderful chance and guilt from how I was to him. He actually called me cold hearted but honest (he didn't say it in a mean way).

I went on a few days later and explained my history, but he only said "I understand, no hard feelings."

Now I just keep feeling so much regret, feeling like I will most definitely never find someone. I try to stay occupied so I don't think about it, but it always comes back. I don't know what to do.

Any suggestions or questions to help me sort through this a little more?
