First of all, I want to tell you that God wants you to be happy. That's not any special knowledge that I have, that's just what He wants for everybody. Being happy, however simple it sounds, is quite complicated. But if you're interested in getting a little bit of an idea on how to live a happy life, please check out my Life Pointers area.
And, of course, you can just do what I do, which is love everybody, no matter who they are, and also live by the Golden Rule, which is do unto others as you would have them do unto you. Praying for folks that need it never hurts either. And I want to stress that you never really have to pray to any particular god, because no matter what religious background you have, you can always pray for "good". About your other problems...
Missing "the one" is a trap set up for you by your mind, or by your ego, I should say. You don't MISS "the one". It's simply not possible to miss the man you're destined to spend the rest of your life with. The Holy Spirit lovingly nudges everybody toward the "love of his or her life". Knowing that the best thing that can possibly happen for you WILL happen for you is one of the qualities of successful, happy people. So, please don't dwell on the idea that you're missing, "the one", because that is a fear that should be avoided or just ignored.
This gentleman, since he has been hurt in previous relationships, is probably not in any rush to get in to another situation that he might view as being POSSIBLY "hurtful". So take your time. Be supportive of him. Don't use any ultimatums, as people tend to do, but instead let yourself enjoy the time you spend with him. He'll respond much better when you're giving off vibes of love and support instead of vibes of fear and doubt.
What I'd like you to remember most of all: Don't worry about time. Don't rush things with this guy OR with anything in your life. Our souls have eternity to do everything we want to do. :)
One more thing, watch for your guardian angel. He or she can probably give you some really good advice when it comes to matters of the heart. If you're not used to communicating or realizing your guardian angel, check out my page about Guardians.
I'll definitely be praying for you and your gentleman friend. I'll also alert my buddies upstairs, as well. So...
Remember now, you've got angels working for you, 24-7. Fear is gone. Believe that, and your life is...heaven...
