I'm not sure there is such a thing as THE feeling or THE one. I know that you as a human have a lot of tools to work with when it comes to making decisions of this caliber. First you have experience and a thinking brain, or you wouldn't be asking questions. Use those tools to ask yourself what you want out of a long term relationship, what you have in common, what you do not have in common, and how each of those really weigh in to your priorities and his. That's the unemotional part of the decision. "That feeling" is an emotion that can wax and wane with the day, the way you physically feel and the circumstances you find yourselves in, so personally I can't put a whole lot of importance on it. Don't get me wrong, it's important to be in love, but not just with the feeling. It accompanies your respect for him as a person, his ideals, his goals, his gifts, his problems, and the way he handles those problems. That in a nutshell is the feeling. The feeling may come and go, but character seldom changes. Get to know his character, beleive me, it will be worth it in the end. Study the way he reacts to good times, bad times, frustrating times, traffic, crowds, being alone, disagreements, etc. etc. Good luck....you can do it !
