To survive a relationship, you need to control your anxiety. When you get anxious, you start doing things that destroy the relationship. When i get anxious for example, i get paranoid. I'm afraid my partner is cheating, lying, or in an accident. I tend to have outbursts and interrogate. I listen to music, meditate, take deep breaths, pray, question my beliefs, work out, etc. to keep me calm. You would be surprised how much your relationship will thrive once you manage anxiety.
