I've been a relationship for a long time with my wonderful boyfriend, but suddenly, I have started to feel doubtful about our relationship. We're going to the same college and love each other very much, but I am worried (I have bad anxiety) that we will get sick of each other and divorce. My parents didn't set a good example which I believe is influencing me, and I'm worried about committing so young. Is this normal? I don't want to break up with him at all but have recently had intrusive thoughts and anxiety about him, and have thought mean things when I get annoyed. He makes my life amazing and I don't know if this is toxic thinking.
