A most excellent post, kp!
True, Andrew, you didn't actually say you were in love. But you did say you were "happier then I've ever been." That would mean happier than when thing were going great with your former girlfriend that you were "in love" with. So naturally, I assumed... Sorry 'bout that. With all the jumping up and down around here, I'm afraid I jumped to conclusions.
Kitchenpete is right. This new relationship is just what you needed to show you that your future is full of possibilities. There will be many relationships to come, Andrew, all of them wonderful in their own unique ways. Enjoy each of them while it lasts, and learn from them. Despite what you may think, a relationship doesn't have to last forever to be a success. Some of the best ones are relatively brief.
Take this one easy, Andrew. Don't force things. Let it go at its own pace, and see where it leads you. Life is full of wonderful surprises if you live it that way.
