I see from your profile that you're 19 years old. In a way this might be a good opportunity for you. I agree that you should do the things that interest YOU even if they didn't work for one reason or another when you were part of a couple. It might also be a good time to explore things that you were curious about but didn't have time/emotional permission to explore when you were involved, and I don't mean just sex. Do you like to travel but your master liked to stay home? Did you always want to take a cooking class? Learn to fix your own bike? Being without a partner is a really good time to expand yourself personally.

I also am a big believer in "dating", as in, spending time with people without the expectation of spending ever-increasingly more time with them, and without the expectation of getting ever-increasingly more sexually intimate. If what you are doing with them is fun NOW, and no ons is getting hurt, there's no reason to psyche out how you're going to feel about them next week. This gives you a broader base of experience about how different men treat you, and it gives you back some power in your own relationships.

I'm sorry that you are hurting. Good call kicking this guy to the curb.
