Interesting. It sounds like you really needed this conversation and it helped you in several productive ways. I would urge some prudential caution just because a lot of well intentioned (and awesome people) sometimes forget a little thing called "boundaries" in their euphoria at mentally turning the clock back to a happier place and time. So long as you remind yourself that your relationship ended and ended *for concrete reasons* hopefully you can keep things close enough to advance yourself (and be worth his time) without getting close to breaching ethical boundaries (he does have a girlfriend) or into a dysfunctional relationship where your communication is an almost punitive device. Some people *can* end up in situations where they feel shitty and unhappy...so they go after unattainable men or put themselves in situations where they hurt themselves (for whatever the reason). I don't think you are the type...but I just want to voice some concern cause I really care about you and your mental well being. Exes can carry a LOT of emotional baggage (from the extremely giddy/positive, to the vindictive/angry, to the guilt-ridden feelings) and I hope you are in a secure enough place at Yale (emotionally and mentally) to know what you are doing and to handle yourself. You might be playing with fire. Just be aware of that and *hopefully* you will be fine.
