I'm falling for a guy that's taken what should I do??!!?

So I recently started a new job about a month ago and I work with this guy who is about 6 years older than me he has 2 kids each from different women but he is engaged and I'm starting to fall for him I tried ignoring my feels toward him but it's hard to we have this really strong connections with each other and we have both talked about it and he feels the same we could both tell before we started talking and so can the people around us we have tried not to take things any farther but and we still haven't but I have a feeling it's going that way is it wrong that we both feel this way?!! Should I just find a n�e job?!
