I am single today because I was not adhering to God's plan for dating. When I finally told God that I wanted things his way. He led me out of the singleness desert and the USA as well. Since then it has been amazing and I should be married pretty soon. I do not say that every single is in the desert, but if you are like me, you need a catalyst and or breakthrough to really get moving. If it is in your heart to marry get with God, expect him to do something, and rely on his strength and grace to get you there.
I once attended a singles seminar. The speaker for that day prophesied that half the singles in that room would be married within a year. (there was maybe 300 people) The response was great. I even a had a woman I knew from work really thinking it might be me as she was there too. (Sorry, I passed on her). Was such a prophecy absurd? Absolutely not, because God is in the marriage business and He puts those desires in you. No one tallied the results but there were people there that married. The problem usually is that our flesh is in the way. We may lack knowledge of how to be successful, and we can lack confidence or obedience in achieving marriage. My start too included re-reading this teaching that was helpful to me.

Scripture really does support the marriage position. Overweight, older, disabled or even a lack of funds does not nullify God's will in marriage. There is someone for you, but remember the saying that God will pass over a thousand people to find one that has faith. Forget rejection, self-image and all the other excuses and get your eyes on God.
In person and online, treat the opposite sex as friends and start to build your confidence and network. In my case, I believe God told me the exact city where I would find someone. God seemed to suggest I should consider someone shorter than average and I accepted that. No your not likely to get a partner from a list drawn up by the flesh, ( I tried that decades ago) but if you fellowship with God you will get some markers so that you can narrow things down and have a strategy that comes from Him. Sorry I went outside the confines of the question, but if your single receive the encouragement and know the word when it comes to marriage and your expectations before marriage.
There is a scripture in James that says pray for one another that you may be healed. I believe this applies to marriage too. Pray and give help for others that they may marry in the will of God. Doing this will in turn will help you. Why does it apply to marriage? because seedtime and harvest is universal. Sow sparingly and reap sparingly, Sow abundantly and reap abundantly. Sow marriage help in other single believers and you can reap it too. Patience matters too, sometimes we need to focus solely on God and you will know when the time is right. After my last failure with a gf, I waited for about two years. During that time I let go of most of my baggage, set my heart the best I could and expected God to do something and wow He sure did. He will do the same for you. God bless!
