It's OK to justify that a red flag is more pink than red sometimes, but be honest with yourself and know the difference between the two. Here are five red flags that shouldn't be justified.

1. Rough housing. He's no good if he twists an arm or grabs or pushes too hard. Even if he's playing around, a respectful person won't hurt his or her partner.

2. The "Who's that guy?" syndrome. Everyone has insecurities so a little jealousy can be normal in a relationship. But you should know the difference between a little jealous and a lot jealous. If he gives you 20 questions every day, if he accuses you of things that are untrue, if he puts you down and calls you names, then he's way too insecure. And the bad news is that he won't get better. It's just the beginning and he WILL get worse.

3. Listen to your sister. There are exceptions to this rule, but know that your family and friends love you and want what is best for you. If someone close to you doesn't like him, at least consider what they have to say about your new man.

4. What happened to the things you used to do? It's natural to fall in love and have a few of your priorities change. You may spend less time on your hobbies or see your friends less, but don't eliminate these things entirely. Consider it a red flag if your significant other makes you feel guilty for doing things on your own or prevents you from spending time with your friends.

5. He's sweet one minute and scary the next minute. Be with someone who is stable and treats you well all the time. If he has extreme mood swings you probably worry about rearranging your day to make him happy or what he'll be like when you get home. Instability like this will wear you out.

Of course this list just scratches the surface. There are certainly more red flags to heed and, of course, women can be just as guilty of committing these crimes. For more dating tips, visit DatingTales online dating guide.
