Had an affair with co-worker for round 6 months - we were both in a relationship and at some point ready to break up but neither of us really did.

At some point after 4month she told me she loved me after which I went somewhat distant and did not really invest that much anymore.

2 months later she broke up (not cuz of me but apparently someone else, where she claimed she didn't want to make the same mistake again) and I broke up with my gf, too. Thought I was in love with her (maybe still do?) and did everything wrong afterwards (classic begging, being needy, all rookie mistakes - to my defence it was Christmas and the air was filled with love and shit like that).

Got my self together again and went distant again (tried NC but did not really work since we are colleagues, so I decided to keep things business and not talk about too much personal stuff) - worked wonders and she is opening up again.

Now the reason I'm here to speak to you guys: How to get her attraction back? I currently can't be in a single relationship anyway (still figuring how to move out and split stuff between me and old gf) but that girl is hot as f*, so I don't wanna miss out on that while I'm single (obviously).
