Would you quit your job if you became infatuated with someone at work?

I'm a married man and been working through a crush i developed on a co-worker, this has been going on for months. My wife knows about my crush and were working stuff out. I am able to come to my senses when I spend enough time away from work and with my family. But during the week i kinda feel like I relapse. Especially when I to talk to her. I never told her that I have a crush on her but I ume she knows. It feels like she try avoids me, so i do the same except when i need to talk to her. But this makes me feel rejected, even though I'm married and she knows I am. I don't blame her for wanting to avoid me. But I carry this rejection home and feel depressed around my family until a few days p and i'm able appreciate what i have. Should I start looking for another job? I'm not sure if I'm strong enough to get past this crush/infatuation.
