Emotionally-guarded people raise their shields to protect against exposing their vulnerabilities. They are afraid that by dropping their shield, they will be humiliated. They are guarding against emotional intimacy, but a relationship can’t be sustained without emotional intimacy. This is a true dilemma for many adults with Asperger’s (AS) and High-Functioning Autism (HFA).
So as you can see, you will likely choose only one of two options here: You will either (1) continue to risk your heart until you find a satisfying relationship, thus improving your self-esteem, or (2) continue to hide your heart to avoid getting hurt, thus settling for low self-esteem and superficial relationships (which aren’t very satisfying).
