complicated

I once did edibles and my boyfriend and I almost broke up because of it. He doesn't smoke and I don't either but that day idk what got into me and I did it. I swore to him I wasn't going to. Yesterday I hiked with some coworkers of mine and they smoke. My boyfriend was upset that I went hiking to the point were he believed I'd smoke. He still insist I did but I didn't. He now wants me to take a drug test and our relationship will be based on that. I love him so  much and I swore to him and every I love that I didn't smoke yet he does not believe a single word. My coworkers tell me he is having way to much control over me. I honestly don't want to loose him at all. On Monday they smoked and I just sat there in the car with them for an hour. He knew about it because I told him. Yesterday they smoked too while hiking but I didn't and today I'll get tested. I'm afraid I will not pass because maybe there might be a small percentage in my body because I was exposed to second hand marijuana. I'm afraid I won't pass because of it and even worst that I won't when I didn't even smoke
