Let me debunk this guy real quick for you.
"he was starting to only see me as a friend" = Some other girl caught his intention and in order to be with him, he has to dumb you, since she is also flirting back with him and giving him the green signal to give it a go, he has to come up with an excuse to breakup with you, any B. S excuse would do.
This "friend" line has been used by both genders, when trying to dump their partner in order to move on to their next love interest.
Either he's feeling guilty and wants you to ease his guilt by talking to him, so he would say "hey look, even though I dumped her for B. S reasons, she's still fine with me, so what I did wasn't that bad, guilt free" or the things aren't going as smoothly as he planned to with the other girl, so he wants to make sure to have you as a backup.
What do you do? You put your emotional state to the sight and start thinking logically and give this dude a boot for life... unless you want him to pull your strings and be an active part of "his" drama, then by all means do talk about to him.
If you don't respect yourself, he's definitely not gonna respect you either, with how he's proceeding, he does not respect you enough. In the end it's your choice in what you want to do.1

Talk to him. If he's making the effort to talk to you, it means he cares about you.0
