There is nothing wrong with praying and sharing with God how you feel and what are your desires. God wants us to communicate with Him. He wants us to pray at all times. People marry at different times. There are no rules. However, it is good not to rush into anything. Whenever you are in a relationship, ask God to let you know if this is a relationship He approves of. He will let you know and guide you. God has a plan for you, get close to Him so that you will know His will for you, for your life. Fix your eyes on Him in every situation and trust Him.
