Has he lied about drugs before? I find that, more often than not, my gut instincts are correct. Being broke after having $100 is certainly suspicious, especially if he doesn't tell you (or isn't truthful) as to how it was spent.

You need to think about yourself here. If he doesn't want the help, he won't accept it no matter how hard you try. At a certain point, it gets ridiculous. If you feel like you have to snoop to find out the truth - I think that's your answer.

I'm glad you are getting out of an abusive relationship. I know it sucks taking that first leap to being independent but it's very rewarding when you aren't walking on eggshells or worrying if someone is lying to you. I hope everything works out for the best.
