I see that emotionally things are difficult right now and even more so for everyone at the current state of our world.
I'm sure it's difficult, being frustrated at not finding the right one yet. You're not alone out there in this world with this.
I want you to go back and read your post...you are suggesting to follow a "lesser evil" and just find a girl for a one night stand? A lesser evil...is there such a thing? How can an "evil" be lesser? I don't think there is such a thing. Evil is evil no matter how it's placed, something may tell us, "Oh, but it's not as bad as...(fill in the blank)." That's the devil talking, trying to convince you that there is something evil, but making it look like a good thing for you. Don't be fooled by this; stand strong!
Stick to what you are 100% is true and good and that's God and His word. Pray to God about this, He knows your hurt, and talk to Him about it. Tell Him that you feel the need a wife in your life. Meditate on His word as it seems that you are under a spiritual attack here. It may be painful, but just do it! Things will get better!
Here are some verses that come to mind:
James 1:2-3
Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance.
1 Timothy 6:11-12
But flee from these things, you man of God, and pursue righteousness, godliness, faith, love, perseverance and gentleness. Fight the good fight of faith; take hold of the eternal life to which you were called, and you made the good confession in the presence of many witnesses.
James 4:7
Submit therefore to God. Resist the devil and he will flee from you.
Matthew 26:41
Keep watching and praying that you may not enter into temptation; the spirit is willing, but the flesh is weak.”
Romans 6:12-14
Therefore do not let sin reign in your mortal body so that you obey its lusts, and do not go on presenting the members of your body to sin as instruments of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments of righteousness to God. For sin shall not be master over you, for you are not under law but under grace.
I remember I had a friend that was about your age at the time a few years ago. She cried out to me that she was not married and that she was getting older and she felt that she would need to "settle" with whoever she could find. I remember talking with her and it was hard to find the words because I was already married and didn't want to hurt her more. I was positive that there was someone out there for her. About 2 years ago she got married (this was about 7 years later after she worried about never finding someone to me). So it seems that there was someone out there.
Patience is hard a lot of times...especially when emotions are going on overdrive and it all becomes so overwhelming. Find something to keep you busy...try out a new hobby - you never know when you'll find someone. Trust in God that He will find you that one. Nothing is too hard for him.
