If you are asking for opinions, I don't think you should date until its final. While you are separated and just waiting for March to roll around, any guy that you are with will technically be with a married woman. If a new relationship starts now, there can always be the suspicion that you aren't faithful. There will always be the issue that, "well you were still technically married when we were together, how do I know I can trust you?" And later in a new relationship, this can be held against you and may become a source of anxiety.

Best to take the high ground, it will show your values later in life, and, help avoid possible conflict in future relationships. Then again, that's just my opinion.
