To Move or Not to Move?

Suga, my older boyfriend that i have dated on and off for about 6 years, finally broke up for good. We ended contact, which wasn't hard, because he's in New York these days, and i am in California. He calls me because "he needed to talk to someone he trusted" and I of course give in. so we talk for a few days and then nothing for a week. He decides its a good idea to fly to California and surprise me with chocolates, because he knows i hate getting flowers, and profess his love and undying devotion to the fact that he knows I am the one for him. Needless to say all I could think of to say was "WHAT!?!" then he proceeds to tell me that he is leaving for New York and wants me to be on the flight with him. Again I say "WHAT!?!". So my dilemma is processing what i should do. Do I stay here where my life and family are and possibly lose friendships that I have built up solidly over the last year and a half? or do I leave on a wild adventure and open a new chapter with a man I care about, but cold break-up with at anytime? so any outside opinions would be helpful in the deciding process. not telling me what to do, just telling me helpful things i may be overlooking in this decision. Please and thank you.
