Christian opinions only! Pretty long, but please, maybe just a "yes u did the right thing" or "No u didnt"?

So I met this great guy last yr (@ a club on Halloween...I shouldnt have been there, but was. I dont go to clubs anymore), he was drinkin, but he was very nice. He was in town on business & he was 1st to tell me hes a Christian. He was respectful & we never even kissed after several times of goin out. We had connected w/o anything sexual. He was iffy about the distance & would only text every month or so. I finally said I want an actual friendship or none vs having a "sometimes friend". He said he wanted to get to know me better, so we did. After a couple months I had been prayin about a relationship w/him & I felt it was ok to pursue if it came up...it did & I accepted. I had known about his "social drinking" which I think was more than socially. I HATE drinkin since I grew up cleaning up after an alcoholic. He also said he had started chewing & this was also something that bothered me as I felt he was using these vices to cope w/stress at work. He even used the words "self medicating". He said he hated doin these things cuz they made him feel even more awful later & he wanted to get his relationship right w/Christ. I felt he was on the right track. So after we started datin for a couple wks. He mentioned smoking pot last year (another vice from his past that I didnt harp on since it was his past) I asked if he still does it & he said "sometimes". I started thinkin about these many addictions & realized as much as we LOVE each other I just CAN'T LIVE w/these things. I told him these things don't make me love him any less...I just can't/won't live with them. He was always tellin me not to change & I hadn't. He knew I had a problem with these things, but I thought he was on the right track. He said he wouldn't stop drinkin, but he wouldn't do pot anymore & was working on not chewing, but just on the weekends. I told him I wanted to be able to share Christ w/whoever Im with & having Christ as the center of a relationship will make it SO much better...he said "I'm not you". He said he wouldnt do these things if we had kids, so I asked him what about the gf he says he loves? He said it seemed as tho I would always stick by his side, so I told him, "If we were married & these things came up after...I would have". I want what God wants for me & shouldnt have to feel like I have to worry about whether he'll relapse. I said, "What vice or addiction is next?? This REALLY worries me." He has always battled depression & feels as tho the world is ALWAYS after him. His concern was that I had just said I wanted a life w/him & all of sudden sprung this on him, but after the drug thing I started realizing he may not really change forever. I asked him how long I'm guaranteed that he'll really stay drug free & he said, "I NEVER said I would quit forever." I just wanted to tell him before it got TOO far into it since his ex waited 3 yrs. She was the pastor's daughter & was supposed to be a "Christian", but they were havin sex for those 3 yrs. He was willing to commit to no sex until we got married. Keep in mind this was long distance & I wouldve eventually had to give up my family, my few friends & my job to live w/him 2500 mi away (which I wouldve done cuz I love him VERY much). He felt that since I loved him I should just turn a blind eye or act like these things arent happening. He said he doesnt expect me to be ok w/it or accept it, but how else could it possibly work?? This was my first bf & I'm 25 yrs old. I fall hard for guys, but I care for him so much I didnt wanna string it out. I understand it happened quickly, but I didnt wanna pretend like anything was wrong in my heart & I felt strong enough at this point to say Im sorry, but its JUST NOT RIGHT. I just want what God wants for me. He said he'd keep in contact w/me & check to see how Im doin, but Im not sure thatll really happen & thats ok. Did I do the right thing?
