..no never, I think if you're committed to a relationship and you then have feelings for someone else that you want to pursue, then you should end that relationship first..it'll still be painful for the other person but they won't have the lying/deception part of as well and that does make it so much worse...

..I also don't believe in 'you can't help who you fall in love with/don't expect these things' either, you can help it, it's completely in your control...you can't help who you meet and if you find yourself attracted to them but you always have a choice whether to pursue that attraction further or whether to walk away from it and be with your current partner...
