Do you purposely ignore your partner's phone calls? Do you take the long way home, so you do not have to see your partner's face? Or maybe you pretend to forget plans, so you don't have to spend time with them? If you answered yes to any of those questions - you're in a relationship rut.
Avoiding your partner is not part of a healthy relationship. You shouldn't want to perform a magic trick to suddenly vanish. Obviously it's okay to have periods when you're upset with each other but for the most part you should always want to spend time with your loved one.
