I'm 23, I been in a relationship for about a year. He is amazing and been so consistent he is really perfect, but I feel like I have so much anxiety from my past. My previous relationship lasted 5 years and was very toxic emotionally and physically. I want to be with him, but I feel like I'm so stressed about what could happen. I broke up with last night, but I feel so hurt. I just don't know if I'm making the right decision. advice?
