If you want to know if the Lord wants you to get married or not, first of all, don't aggressively pursue marriage. Don't even think about it. Keep the desire at the back of your mind.
I'm not telling you to abandon desires. Just don't let it become an idol. Sadly, many Christians fall into that state and when they hear an answer they think it's from God when the answer simply came from their own mind by failing to control their strong desires.
Strong desires that escapes our control can make you unable to discern another person or spirit. You might listen to the wrong spirits, fall in love with the wrong person (who may not be evil, just the wrong person for you)
Find contentment in being single, in whatever state you are. Even if you do nothing, the Lord can send your way the right person for you. Even if not, if you're content in every situation. It wouldn't be a problem.
Controlling your desires is of utmost importance. If you can't control it, that's the "voice" you will hear and not the Lord.
Sometimes you will never get an answer from the Lord but the Lord is still working on your life and contentment will get you through. Don't pursue things, control your desires, and be content.
