Relationships have their ups and downs, but there's a big difference between a relationship that's going through a rough patch and one that's abusive.
She says that quick involvement in a relationship - someone appearing "too in love", obsessive or possessive from the start - can be an early warning sign.
Extreme jealousy can also indicate an abusive dynamic. If a partner does not want you to socialise with anyone but them, it may be time to walk away.
McGraw says you should also be cautious if you know there has been a history of physical or verbal abuse - be that in your relationship, or in a relationship your partner has previously had.
The six remaining signs to look for are:
- Controlling behaviour
- Threats of violence
- Abrupt mood changes
- Verbal abuse
- Breaking objects
- Use of force during an argument
