If you're not at peace with the idea of remaining single, then it is highly unlikely, that it is God's will for you to be single.
God wants you to move in His divine timing . But this can only be achieved, when you learn to relax and let Him take full charge of the situation. Maybe you feel like there is something, you should be doing, inorder to meet someone. Trust me, when the time is right, God will create that situation, for you to stumble into that special person. Like you might even find yourself all of a sudden, desiring to go to a place that you hadn't planned to visit or you might just leave the house unusually late for work, simply because it is time for you to meet "The one".
Some people tend to say things like, I met my partner totally by accident and yet, what they do not seem to realise is, it had already been established in heaven, to happen that way. Satan can also cause us, to stumble into the wrong people too though. But the only difference is, you will know a God fearing person by their fruits. But if you're still not sure after meeting someone, trust the Lord to reveal to you who they really are in Christ.
