Is unfortunately all too common and is most often found being done to women.
If this is you then the first step is to accept and acknowledge that this is what it is.
Abuse is abuse.
Face it and call it what it is.
Second if you see yourself as a victim then look again.
You have choices
To accept and stay in the situation.
To confront the other party and state your unwillingness to continue receiving this behaviour and state clearly what you feel is reasonable with a clear deadline for a change in the other persons behaviour.
Or thirdly make your arrangements and leave.
You have choices.
Do not stay in an abusive situation.
See reality and move on.
