Well, Orihime has been in love with Ichigo, so it kind of makes sense, since that's what we were given. But, before the epilogue, there was no indication that the feeling was mutual, so I understand where you're coming from, especially if you did skim parts of the manga.

I can safely tell you that there were no parts in the actual manga that covered their relationships prior to the epilogue, as Kubo made it clear he didn't intend to exploit romantic aspects while writing.

However, the epilogue takes place ten years after the conclusion of the final battle with Yhwach, and as such, enough has happened within that time span that resulted in not only Ichigo and Orihime, and Renji and Rukia getting together, but for them to have kids as well.

Kubo however covered nothing within that ten year time span, so we don't know how it happened any more than most of the other fans.
