Am I (24F) wrong to think these comments from my ex (24M) are odd?

So we split recently as he claims he fell out of love. I’ve done a lot of soul searching and realised we did grow apart. There was a moment where I want to reconcile but I realised that’s probably not for the best. We have spoken once or twice in the last few weeks since the break up and each time he comes across a little rude and it became obvious he was unable to talk to me or face me. The reasons we spoke were to meet up and sort out our stuff. I got really drunk and told him I don’t love him anymore. Since then he has been able to speak to me it seems. We spoke recently for about 5 hours, about a lot but there are quite a few things that I felt were odd to say the least.

He has only told 4 people and has only gone into detail with 1 person. Told me he could not bring himself to move on if he new I hadn’t yet. Said he was offered sex multiple times and turned it down. Confirmed he deleted my nude pictures and then said he wishes he kept them for personal reasons. Tells me he’s deleted all of our text messages. Assumed I slept with someone else when I had texted him while drunk. Says he didn’t care. If I slept with a lot of people he would be disappointed and concerned.

I know that’s he stills cares for me in a platonic way however, I find some of these comments odd considering the reason we are no longer together.

My question is, am I reading into this or am I missing something here?
