DP doing drugs, no idea what to do

[Ilovecoleslaw]

DP used to have a really bad coke addiction, stopped when we got together (1 year ago).
Read his messages tonight and saw him getting some.
I know I shouldn't have read his messages and it's my fault for snooping but it seems I'm right on this issue.
The last time we spoke about it I said I couldn't be with him if he did it again. He swore to me he would never touch it again.
I am so upset and I can't think straight.
Please help me think this through.
Idk whether to tell him not to bother coming home or see if he lies about it in the morning.
Can't stop shaking I'm so mad and upset at him
Aibu to feel this way?

This may sound harsh, but it's the truth; If you continue this relationship you will have no one to blame but yourself for the misery that WILL be coming into your life. He can't be trusted, and if you allow him to stay, he will never change. He's shown you who he is and I suggest you believe him.

If you keep forgiving him every time he does it, he will keep doing it because he will know you will keep forgiving him. Addicts need a reason to quit.
