I think being single can be stressful just knowing you have to make it on your own. A marriage can also be stressful because partners can have different views on things, working together isn't always that easy. For the question about advantages, when you're single you don't have anyone to answer to, but when you're married it's nice to have someone to come home to.

32 Indeed, I want YOU to be free from anxiety. The unmarried man is anxious for the things of the Lord, how he may gain the Lord’s approval. 33 But the married man is anxious for the things of the world, how he may gain the approval of his wife, 34 and he is divided. Further, the unmarried woman, and the virgin, is anxious for the things of the Lord, that she may be holy both in her body and in her spirit. However, the married woman is anxious for the things of the world, how she may gain the approval of her husband. 35 But this I am saying for YOUR personal advantage, not that I may cast a noose upon YOU, but to move YOU to that which is becoming and that which means constant attendance upon the Lord without distraction. 36 But if anyone thinks he is behaving improperly toward his virginity, if that is past the bloom of youth, and this is the way it should take place, let him do what he wants; he does not sin. Let them marry. 37 But if anyone stands settled in his heart, having no necessity, but has authority over his own will and has made this decision in his own heart, to keep his own virginity, he will do well. 38 Consequently he also that gives his virginity in marriage does well, but he that does not give it in marriage will do better. 39 A wife is bound during all the time her husband is alive. But if her husband should fall asleep [in death], she is free to be married to whom she wants, only in [the] Lord. 40 But she is happier if she remains as she is, according to my opinion. I certainly think I also have God’s spirit. 1 Corinthians 7: 32-40

I love being Single -- I can be myself, and don't have to be treated bad -- I'm a lot better at being by myself

You can only enjoy being single if you have already been married. And then, yes, it is divine.
