Welcome Kersyn and so glad you found us. Although I'm very sorry for what brings you here.
As Queenbee and Anvil have already said, this is what addicts do. You may expect the disappearances to be a regular occurrence with this man.
Most of us here found we were not happy in a relationship like this and got out (Yep sleepless nights, wondering if they are dead, anger when you finally learn they are okay.) Please think carefully about what you want for yourself.
And I know that this is a super, super glow-in-the-dark painful decision to have to make.
Please keep posting and let us know how we can help.
