<human>: I broke up with my boyfriend of 5 years 3 weeks ago after a slow realization that I was no longer in love with him. I had spent the past year of our relationship trying desperately to see if I could fall back in love--but my heart was no longer in it and it wasn't fair for me to 
string him along.

Yesterday he contacted me basically begging for me to talk to him because he seeks 'closure' since he felt our breakup conversation was too short. I disagree--I first broke the news to him and then met up with him later that week and explained what I said in this post and more. 

What makes things difficult is that we share a huge amount of mutual friends and they are all insisting that I speak with him again. I personally feel like going into the details of things won't make anything better. For one, I don't want to date him anymore and I'm afraid he will try to win me back with the conversation. They are making me feel like a monster for not wanting to meet up with him and discuss things.

Second, my answers are probably not going to satisfy him. There wasn't a single moment or action that led to my decision. 

Last, while I was upset the first few days I've been feeling pretty great otherwise. My professional life is going well, I've been exercising, reading and enjoying my freedom and alone time. Talking to him yesterday has put me back to square one with feeling shitty with all my feelings of sadness and guilt.

If I do talk to him, I want to do it over the phone. When I said this to him he insisted that "he's not having this conversation" over the phone.

So do I owe him closure? It is reasonable that I do not want to meet up and would rather have a phone conversation?

Can you summarize the given text in a few sentences?
<bot>: Ex wants closure after I broke up with him 3 weeks ago. I do not want to, and if I must I want to talk on the phone and not in person.
