Can a Separated Catholic Receive Communion?

I am separated. I was only married for a month and it was never consummated, and it was outside of the Church. Can I receive communion?

Yes! In the eyes of the church you were never married if this was simply a civil ceremony. The marriage not being consummated is also grounds for annulment. It sounds to me as if you would like to dissolve this marriage. I would talk with your pastor about all of this, make a good confession, and then you should be free to receive communion.
