Most Helpful Guy
You can't stop and attraction, you just have to deal with it. When you're with a guy or girl (if you're a guy), it doesn't mean that you should suddenly not find anyone attractive anymore. The goal is to stay loyal to the one you're currently with, and you're the only one that knows the answer to it.

Bear in mind here, dear, be strong as well, that he Is Not only 'Married' But------He's my supervisor.
Although you are finding yourself 'Hard to avoid him,' one thing I am sure you are also having trouble forgetting is that you have a 'Boyfriend of 5 years' and hopefully still counting and that with your mad crush that is like this 'Sweat shop,' probably even after the doors close at 5, there may be trouble in paradise in your own relationship, where your wandering eyes and thoughts are... brought to the job with you.
If you are in this rut with your relationship or there is War of the Roses, it's time to do some soul searching about even staying in this romance. With This perhaps, instead of working over time on 'This guy randomly,' might take your mind off things a bit and maybe find someone else who is more suitable for you... on both sides of the coin.
Good luck. xx
