Would you wait for someone who asked to for time to end their current relationship?

Basically you meet and have amazing chemistry but find out they’re seeing someone

They refuse to cheat but also are no longer happy

So they ask you to wait for them while they break up with their current partner before you start seeing each other

Would you do it? Or would it still feel like cheating/home wrecking to you

(Keep in mind the person in question is everything you want in a partner not just some random fling)
