keep in mind hon, that when you met him he was using and you didn't have a clue. and that was only six little months ago. half a year. it's great he seems to be doing the right things now.....but he's only been sober for a month or so now.....that's very very early sobriety. as it is, he's still having trouble following the rules at the sober house....or at least that is what he said when he missed the lovely dinner you planned.
slow things way down. give time time. you are just starting out yourself...first apartment, first job. keep your eye on the prize here, which is your own fabulously wonderful life that may or may not include him. and you will be ok either way.
