Extremely confused, need some advice (be warned, story's a bit long)

[PFlyers]

I'm just afraid that since there's this girl who he's also at odds with if I back off he'll just move on with her and forget about me. It's just confusing because even though this has all been very recent, he shows absolutely no signs of acknowledging any sort of a change in our dynamic and is going on as if nothing ever happened, as in he both continues to flirt and try to have long text conversations, etc., but still never brings up the topic of how he feels, even when I've offered to be there for him if he wants to talk multiple times...
