Had to dump my ex…

I am 32 and he is 29. I got back with my ex after 13 months, we dated for roughly 3 months beforehand, and told him I realized I made a mistake of knee jerking us and how much I missed him and how I wanna try things again. Well I ended up dumping him again after 6 weeks into dating and here are my reasons. He invited me to his swearing in as an attorney and his parents were there along with his other friends. he let me know beforehand that his parents were gonna be there and not to think anything weird like it was a meet and greet I said OK. The following week him and I met up for dinner after work and we were both extremely tired and it was a more quiet dinner, and then a couple days later I came over to his place and noted on his counter was CBD oil and that was my final straw with him, as I’m in the military.  I text him the next day saying how CBD is a major red flag for me and he was confused as to why I couldn’t have a healthy conversation the next day instead of dragging things out for ten days via text when we finally had our phone call and I also told him how I was extremely upset that his parents were there, and how us having a quiet dinner just meant that we don’t have anything in common. He explain the CBD oil helps his anxiety (the stuff you can buy over-the-counter at the grocery store apparently) I said don’t care what capacity it’s used in, I think of pothead losers when it comes to anything hemp related. He asked me why I even came back if I was so quick to find excuses and not work through things, he also mentioned how my problems aren’t even real issues in a relationship and how I had unrealistic expectations so soon into rekindling to use what I said above as reasons to leave. He offered to stop CBD oil if it bothered me because he cares and values the relationship enough and how he doesn’t even depend on it at all and I said no I don’t care if you stopped for me, I said if I knew you did CBD I wouldn’t have wasted my time dating him. He said he didn’t think it would a huge issue nor felt obligated to just randomly volunteer his medical history to me. I just said this isn’t working for us and all of this is a compatibility issue. He’s upset and confused and that’s fine, he’s allowed but all of this gave me the icks. We had fun though and I text him that I was glad we met and tried things again. I did offer if we could be friends and he said no, finds it a slap to his face???
