my bf and i have been together almost 6 yrs. and have spent practically everyday together.and i'll admit i struggle sometimes with co-dependancy. this weekend he is going to his friends bachalor party to a lake, whihc wouldn't be bad except for some of the other people going i don't trust. one guy inparticular is a huge drug addict...my bf has previouly dabbled in drugs but doesn't now however there are times he'll occasionally partake. he knows this really bothers me, i find myself panicing that when he goes this weekend he's going to partake, and not tell me or soemthing bad will happen. its about twenty guys on a lake, i just keep thinking their all going to find random girls on the lake and if theres drugs no telling what could happen. like i said most of the guys i feel like will be fine and be enough to really keep my bf grounded and not do anything crazy, but i still have these thoughts and they are bothering me. my bf hasn't really given me a reason to think hes going to go nuts so i don't know why i keep thinking these thoughts....the only thing i can think of is because of this particualr guy going, i have never trusted him, and i hate when my bf is around him period, wish they never became friends, and he's annoying on top of it, feel like he's using my bf as well as other people. are my fear irrational and what can i do to help myself not think about the bad and let my bf enjoy his weekend with his friends and me to not drive myself crazy
