<human>: Could you distill the essence of the text into 1-3 sentences?

So I've been dating this guy (his first homosexual relationship) and helped him discover himself as bi, we promised to remain friends no matter what. He comes out to most of his friends and family while we were together, we broke up due to some issues. Pretty mutual and 6-7 months down the line (now) he's uncertain as to whether he wants to meet up with me.

He told me that he would meet up with me on the condition that I didn't say anything about the relationship we had or make any references to our past. I responded by saying that this would be near impossible in my eyes, due to how I've known him. Our memories would have to be wiped and we'd need to be strangers again. I said that I wouldn't mention anything about the relationship but I'm also not going to pretend like nothing happened either.

He tells me that he's "completely" over the relationship, but I'm still confused as to why he feels fearful/uncomfortable over meeting up even if we do talk about the past. Surely if you were over something, it no longer makes you uncomfortable talking about it? In regard to this, he also reminded me that he was the one who ended it, not that it's relevant to moving on (so I replied).

He said I was cold for saying that I no longer felt sad over our relationship but nostalgic. I then explained why I felt how I felt; things didn't work out between us, it would therefore not have worked in the long run. It is how it is, you've just got to accept it. And how I take away all the good times/memories from the relationship.

Additionally, just some background on him. When his dog passed away, he bought a new one the next day. And he tells me he gets upset and cries over his grandad's memories. He's also dating a girl since August this year and aggressively claimed to me that he's no longer bi, when I asked him to tell his girlfriend about the meet up if he felt necessary. Note, previously when we were together he told me that he believed sexuality is given from birth.
<bot>: EX says they're completely over the relationship, however they're uncertain about meeting up due to risk of talking about the past. Situation is confusing me and I miss the friendship.
