Simple yes or no question
I think you can.
My sexual desires for another woman has nothing to do with my love for the woman i love. Now, mind you, the act of cheating itself can hurt the woman you love. But the fact that you are cheating doesnt mean you love your woman any less.
Edit: I think once we as human being are able to separate love and sex it will be clearer. Im in love with my ex. She's engaged to another man. She still loves me and I love her. She loves him too. I have no problem with her being with him abd she understand that i date other women
