1. One-sidedness: when a relationship becomes a one sided thing, it is no longer a relationship, but more of a fan, or hero-worship type situation. This is highly unhealthy. Evaluate your relationship. Are both parties making efforts? Does one party do more than the other to keep things going and smooth? Then change this. Sometimes a relationship becomes one sided because a certain party is forcing things that are no longer coming naturally. When that is the case, it is time to make changes, or leave the relationship. No one feels good, or has good esteem in a one sided relationship.

2. Abuse: If there is abuse of any kind in a relationship, physical, mental, or emotional, it is an unhealthy relationship. There are probably times in every relationship where some form of mental abuse takes place, but the fact is, this does not make it okay, and consistent patterns of putting someone down, or making them feel inferior, physically abusing them, or making love conditional is not healthy and should be avoided. It is often hard to recognize abuse in your own relationships, but the fact is, if abuse is happening, seek counseling, or get out.

3. All work no play: When a relationship turns into something that is all about work, and responsibility, and there is no fun or play in the relationship, the relationship is in danger. This is a common problem in marriages, where the spouses get so caught up in their responsibilities of earning a living and raising children that the relationship becomes all work and no play. This is not healthy, there needs to be balance and fun for love and happiness to grow.

4. All play no work: A relationship that is too much fun, with no real substance is not going to last. It is flimsy. The first trial is likely to blow it over. The idea of a relationship that is tons of fun is appealing, but there has to be balance and something to ground it. There has to be reality. So, don't let your relationship be based on having fun without any substance to it. It is okay to sit at home or clean a room together, or work through a problem together every now and then.

5. Talking to others about your relationship problems: A huge relationship no-no is when you start telling other people about your relationship problems. If you start trash talking the people in your relationships to others then there are some real problems in the relationship. You need to learn to confide in one another, and work through your problems privately. As soon as you drag other people in, you put the relationship in danger.
