Wanting you to spend all your time with them, controlling what you wear, say or do are all danger signs of an unhealthy relationship. Remember that the abuser is acting from the need to feel powerful and to be in control. In a healthy relationship each partner wants the other to continue to grow and develop as an individual. There are cycles in all relationships, even the healthiest relationship. In an abusive relationship these cycles are more pronounced, often seem more dramatic and can happen in a quicker time.
All relations have a period of tension building.
This can be productive in a healthy relationship because it brings differences and concerns to the surface where they can be talked about and resolved. Following the tension building, relationships go through a 'honeymoon' period where you feel like you are falling in love all over again. The abusive relationship has cycles too. The tension-building period does not lead to a healthy discussion of problems. The abuser may call you names, make threats, or in other ways attempt to make you feel badly about yourself.
