king abandon

the other day was the second time in my life that i sabatoged a relationship in my life over something stupid. this time it was about me smoking weed. my girlfriend and i were seemingly happy, but she didnt know that i smoked as often as i did. the result skyping her high…she didnt really notice just thought i was being more silly than usual. anyways she found out. i didnt deal with it well, other people were fighting in my life and i was stressed. i took up the same stance in the arguement when it came up a couple months ago and that was u either put up with my choice or go. in my opinion i was doing the right thing. i know it wouldve just changed her into a person she didnt want to b just by being around me. i didnt want to accept responsibility for that down the road. she had no idea the path that wouldve been in front of her if she had to put up with it. my reasoning is simple, people around crime become more accepting of it and sometimes fall into it, using that same ideology on being around a pothead, in my opinion she wouldve become accepting to slack behavior and possibly even travel the road herself. i couldnt have that. i couldnt ruin her life.
i feel bad about my decision because aside this one issue she did put up with it. but she felt hurt that i skyped her, and my stressed mindset refused me to see it as anything but another complaint. it wasnt, she was legitimately hurt and wanted me to make it better. so i broke it off. i hope only that my decision was right, because we were incredibly happy together, even if it was for only a short time.
still though i dont know if i couldve found a better way than what happened, my mind seeems unable to come up with what if’s in this situation.
