<human>: I dated my ex for several years before breaking up with him in a very harsh way I regret. I was single for a couple more years, only a couple minor relationships, until I met my current boyfriend almost a year ago. My current boyfriend is amazing and I have every intention of marrying him. We have a lot in common and very similar attitudes towards life and love and the future. We rarely ever fight and when we do it's usually easily resolved with a conversation. I feel incredibly blessed.

My current boyfriend has a lot in common with my ex. Pretty much everything I liked about my ex, my bf also has. But everything I disliked about my ex, my bf has the opposite of. When describing our relationship, I have referred to my bf as version 2.0 of my ex. Everyone laughs at how much I stick to my type.

Apparently, my ex somehow heard all of this. He emailed me raving about how I'm clearly still in love with him because my boyfriend is so similar to him. The worst part was when the email just became him confessing that he still loves me after all these years, how he thinks we can make it work, and all sorts of things that just made me pity him.

I do not love my ex anymore. None of his email made me want to get back with him and the thought of it sounds terrible. I haven't talked to my bf about all this because I don't think he'd react well and I would rather just deal with my ex somehow. Should I just ignore him? That feels cruel. I want a short message to tell him that I don't love him and that he needs to move on, but I feel like I've said that to him before... How can I be firm but succinct?

Can you give me the gist of the text in a nutshell?
<bot>: Ex is sure that I'm still in love with him based on similarities between him and my current bf. Ex confessed love to me in an email. Best response?
