1. Deception
Lies can shatter trust, the most important foundation in a relationship. Once he has deceived you, it's time to rethink your relationship and future.
2. Violence
Violence is unacceptable in emotional relationships. Do not succumb to his physical abuse; this should be your bottom line.
3. Indifference
A cold and aloof man always has a fatal attraction for women, but you'd better figure out if he's just cold on the outside or cold on the inside. If it's the latter, you'll find it hard to tolerate him for long.
4. Bad temper
Everyone encounters things and people that make them angry. But anger and losing control are two completely different concepts. A partner who expresses anger inappropriately (such as throwing things or yelling) can have disastrous consequences for your relationship.
5. Lack of respect
If he shows disrespect to you in any way, don't tolerate it. It only shows that he is not worth entrusting your life to.
