breaking up as a relationship fix?

things have been going really great w/bf & i. we are getting along great, having fun, feeling in love again. it seems like the relationship has a new life that was born out of our breaking up.

bf seems to be appreciating me, and making an effort to improve things with us.

i still have concerns but hopefully those will slowly work themselves out. i'm still holding back, not allowing myself to get too close. but we'll see.
