I agree with what others have said. This is absolutely not the time to get your heart involved with another woman. Accept her friendship at work, but nothing more.

If there is the possibility of a romantic relationship in the future, you want to come to each other whole, not burdened down with going thru a divorce. You need time to grieve your marriage.

If you started a relationship now, the dynamics would just be wrong, and could be very hard to shift down the road. She may want to nurture and mother you during your time of need. And that may be very appealing. But once the grieving is over, you may be stuck in that dynamic. You want a relationship where you are both whole and the nurturing is equal.

And you've potentially thrown away what could be a fantastic relationship in the future for a short term relationship of seeing you through your divorce.
