I agree with suzane0beyonce. Not only that but it gets to be waayy too much to see your beloved in the evenings, and also in the daytime at work when you're supposed to be able to be your 'work self' (ie: your own, individual self, rather than part of a twosome).
I once dated someone I worked with, he didn't even work in the same office as I, just another area. After awhile I got so sick of him constantly around, always coming in even when other people were in my office, always disrupting my work. My love is very important to me, but so is my career, and mixing the two [usually] greatly disrupts the balance.
