What is most important is to humbly serve the Lord doing the best with what He graciously provides. Personally, I believe companionship makes this life's journey more meaningful sharing the experience and growing together spiritually. If you are lonely it is wise to pray for God to search and find a loving and faithful person to become your spouse. Speaking from experience if you leave God out of the selection process you will most likely certainly regret it. Without the commitment of marriage any relationship becomes a house of cards that will certainly collapse after the first storm.
