LDR ending because of a possibility

Miss

I'm almost certain my long distance relationship of 7 months is going to end because of a stupid what if. A stupid improbable possiblity. I've told him from the get go, weed isn't something I ever want in my life. I don't associate with people who partake in it actively. He told me months ago that if he won the lottery that he'd want to smoke weed everyday. I told him I wouldn't stand behind it.

Today we agreed we would both be happy if we could cuddle all day. He then said he needs to win the lottery so we could do that. Then I responded with I thought he'd smoke weed all day. His response was yeah. So again I reminded him that it was a deal breaker for me. He asked why did it matter if we were in diffstates. Yeah, that response killed, but I told him it didn't matter if I was standing next to him or on the other side of the world. I wouldn't cross paths with weed.

He now says this needs to be dealt with tomorrow.

He's the absolute perfect guy for me, but this is truly one of my only deal breakers. But if he can choose a possible life with weed over present me, I deserve better. I know this, but the possibility of it all ending kills.
