The odds of finding true love online are about the same as finding true love in general. Unfortunately, you have a long road to tread. However, there are other things to consider. It is wonderful that you are very excited to meet him. However, you may consider meeting him in a public place for at least the first encounter.
Love is always a gamble.
I am a fan of trusting your instincts. However, you cannot trust your instincts about him completely until you meet him. Face to face contact may give you new feelings about him. Listen to your heart AND your head. Dear Destiny, I am 41, He is 68.
