Emotional disconnection

Once Im heartbroken or cast aside my brain slowly switches over and I just disconnect emotionally and physically and eventually mentally. Right now I havent been with anyone since November and it took little time (few months) to cut them off once they violated my love/trust. Is this truly a Sagittarian superpower or am I just emotionally repressed?

P.S Ive made a vow to myself to work on my life before trying to find love in hopeless places. Sure I can emotionally disconnect but I also emotionally connect to fast before seeing the red flags sometimes.
