I am just taking the high road here with you, I am a very outspoken person so I would have approached him a long time ago and ironed this out fast. I would take him aside and let him know that struggles you are going thru with this and how very hard you work to make sure you are safe and happy. Let him know the results if you do NOT and by all means let him know this scares you. Sometimes if people don't actually have or know someone who has a disease, they don't realize the struggles that we that do go thru to control things that are involved.
This is given he is an all around good guy and he really likes you and this is why he is "picking on you". I know that sometimes it can sound brutal, but it could very well be that he genuinely likes spending time around you and this is how he shows it. Guys are some funny creatures when it comes to this. No offense to any guys here, but in general guys never grow up and picking on a girl can mean anything from he is a genuine jerk to he has a crush on you and it is hard to say which is which.
I would definitely pull him aside and let him know that this bothers you though. He may be a jerk about it at first, but if he is a genuine good person, and this is just his way of ribbing you, he will be more sensitive and if he isn't then take it above his head.
NO JOB is worth this insanity, that can be replaced, your sanity and self preseration cannot. I have quit a few very nice jobs because they didn't give me the respect I deserved. I had one guy get all over me because my son got hurt at school and was taken to the hospital, he told me if I left not to come back. I didn't. They called me a week later and asked me to come back, and I didn't.
Bottom line is YOU are responsible for your own self preservation and no one is going to protect you if you don't do it, if this is not ok with you, then YOU have to confront him, you can do it with respect, but you have to do it.
