My story starts before I was even aware what was going on. My boyfriend has been using cocaine for about a year and struggles with it. It has taken me a lot of time to gather the information on what to look for in his behavior and how to spot his high. He has gone into absolute rages at me, pleaded with me to stay with him, promised he would never do it again, but ultimately does. I gave him the final ultimatum a few weeks ago, and he is dead pan that he will never touch it again. I am scare because when he is on something, it is not easy to tell. I know him deeply, so it's easy for me to spot (now) but he is smart...I am worried that he is finding other ways to use that aren't as noticeable (no one has allergies and runny noses so intermittently. Lately he has had a racing heart beat, seems paranoid and anxiety-ridden and also doesn't eat much (even though he loves to eat). I have no idea what to do. I don't want to be constantly checking in on him as he doesn't like feeling like I am untrusting and always checking in. Does anyone have any advice on what to look out for?
