<human>: Can you succinctly summarize the text in 1-3 sentences?

My SO (22) and I (20) were together for about 10 months. We broke up about 2 weeks ago because he is graduating college and he "needed to get his life in order and didn't want to worry about me." He said that he still wanted to spend time with me and take me on dates, but just not have the title of boyfriend/girlfriend. 
I'm still very in love with him so whenever he wants me to stay, I stay. Whenever he wants to do something with me, I'll do it. It's now gotten to the point where I'm sick of giving him all the comfort he needs, but him not giving me the stability I need. I've also heard from friends of his that he is talking to other girls but yet he still wants to hang out with me all the time. I want to end all of this on my own terms and stop being used whenever he is lonely.. So that's essentially what I need help with. 
First: Is it selfish of me to want the exclusiveness of a real relationship? 
Second: How should I break up with him? (What to say, how to act, how to move on..)
<bot>: Ex-boyfriend still wants to hang out with me all the time, but doesn't want to be tied down to a real relationship.. which is what I want. How should I end things right?
