Hey hopepraylove...so sorry you're going through this
It's important for you to take care of yourself right now. You did the right thing. Focus on your new job and your new apartment. You don't need to tell someone you're going no contact - you just do it. Let go & let HP. He's broken your trust - I can't tell you what your boundaries are, but you should ask yourself if lying to you is a sign of love.
We all love our addicts and want them to get sober. That's why we're here. Unfortunately though, it's not up to us and we have to let go because we have no control. Good luck to you - I hope you find the strength to embrace your new journey rather than dwell on the "what ifs" about life with an addict. Hugs to you!!!
