When does "piecing" start?

I think that she should feel differently towards me

That's probably the stumbling block. That is probably what keeps you two stuck and on script. You're both working off feelings here: her wanting to feel love, you wanting to feel loved.

Ehhh just deal with whatever is happening (pleasant or otherwise) without projecting your expectations into every interaction, deal with her like you would a new person in your life without all of that negative history, and try to have some fun too

You have any guy buddies? Go do something different. Somehow you need to shift your focus back to yourself and being positive.
