You’re right — when things move too quickly in one direction, they could easily move as quickly in the other direction. The timetable I give people is to use the first three months of dating to simply decide if you want to continue dating. This slows things down, but it also gives you both the time to really get to know each other. If you like each other enough to continue dating, use the second three months to decide if you want to be monogamous. I think this timetable, while slow for where you are, is going to help alleviate your anxiety about whether or not he’s the one. Let me know if that helps.
