I’ll be very honest with you. It doesn’t sound like a healthy relationship for YOU.

Regardless what’s going on with him and what causes him to mistreat you in such manner, your health is effected (I doubt there is a single person on this planet who’d not have issues because of this treatment).

Now if he was a family member, long term friend or life long spouse, I’d say let’s see what’s happening and let’s salvage it. But if this is a fairly new relationship, and he already treats your poorly, it has nowhere to go but downhill. Relationships starting in this manner rarely if ever turn into a bliss. Him just disappearing is a bad sign (substance abuse, shady dealings, who knows what else).

I am sorry. Sadly we can’t get people to change their ways. They either change it on their own or we have to accept their behavior at a face value. It doesn’t sound like accepting his bad behavior is healthy for you at all. You deserve a happy peaceful life and not struggle like this
