Dont ask her out again.
Has she dated anyone else since yall have been getting to know each other again?
Be alittle forward. See if she wants to hold hands. DONT ASK for God's sake. Just take her hand one day. Or play with her feet if yall are watching TV together. Tell her small things, like you like her hair, or eyes. Let her get there. Trust me, it'll move forward if it's meant to happen.
One I don't plan on asking again, two, no she's single and I agree with you on the rest. That's what I've been doing, it's been going pretty good.
