Hey Melanie99. By your screen name, I can't help but wonder, are you sixteen years old? It is common for people to put their birth year in their screen name, so I thought this might be the case.
Well, if in any case you indeed are sixteen, then I would encourage you in your wait and in your time of prayer. Now being 25 years old and almost 26, I can safely say my character and identity has down leaps and bounds in growth since I was sixteen and I am so much more aware of what it means to love someone and to be loved back. And even in all this time, I'm not completely sure that I am ready for a serious relationship.
But I guess that's me, and you're you, and we're two completely different stories. Well, even if you're not sixteen, what you are doing is completely wise and awesome.
We start relationships with the intent on marriage, because at the end of the day, that's what dating or relationships are aiming towards. The most important decision you'll ever make, is who or what you worship, the second most important decision you ever make is who you marry.
Our God is a wonderful Heavenly Father, and he's been doing the daddy business for a very long time so He knows how to look after us, guide us and give good things to us. He knows the desires and needs of our hearts and He takes great joy in fulfilling these needs. He has the best advice! More than anything else He wants you to take His hand and let Him lead you to right person in the right season, so in saying this, He wants you to depend on His voice and where He calls you to be.
That is just my elaborate way to say I think you're doing the right thing.
