Hello!
I’m sorry about what brings you here...
This is not flippant: celebrate! Celebrate that you have started your own journey into healing. Celebrate that you have put your self first which is the right thing to do. Sometimes one of the best things we can do for an addict is to let them go with love. This doesn’t mean that you don’t love him, it means that you love yourself more. Count your blessings that you did not have a child with this person, that would make things much more complicated and tough.
Hang in here, get some support and really embrace this moment. It is hard now but it is the beginning of a new life without the pain, drama and baggage. Be proud of yourself, you are strong.
