You're in a relationship with a great person who you love. You've developed TRUST, established BOUNDARIES, and learned each other's communication styles. At the same time, you might find yourself constantly questioning yourself, your partner, and the relationship. Will things last? How do you know if this person is really the right one for you? What if they're hiding some dark secret? What if you're just incapable of maintaining a healthy, committed relationship? This constant worrying has a name: relationship anxiety. It refers to those feelings of worry, insecurity, and doubt that can pop up in a relationship, even if everything is going relatively well.
