Things have become so bad that honestly it doesn't seem like marriage as most know it today helps most people all that much. There is divorce and adultery all over the place, and when a spouse goes astray in regards to their faith, in many cases the other spouse is extremely tempted to passively follow for fear of winding up abandoned by their husband/wife.
I just really don't think married people have it way easier than we single people do. If anything most probably have many days when they feel very flustered or stressed out or otherwise smothered by each other, while those of us who are single don't have to deal with anybody. In some ways it is much easier being single. We don't go through the same trials (of many sorts) that spouses do. Neither do we enjoy the benefits, either, of a loving marriage that Christ-focused. But again I don't think they somehow have it so much easier. For example as singles, we typically serve who we choose, on our terms, when we have the time, energy and health to do so. Spouses need to be supporting and patient and loving to each other every day, day after day, year after year, and I'm sure that isn't always easy, so say the least.
As far as "sexual purity" well before I was saved, I dun goofed multiple times, so I'm not one to give solid advice on that. Now that I am saved, it's kind of cool and weird, but I wanted that temptation out of my life and out of my life it went, along with several other temptations. So I guess my advice there is to ask Jesus for help. Worked for me.
