Knee-Jerk-Feelings of the BEAST
That "jealousy" is 100% Beast. IT has had free reign with your emotions for many years, and now that you have separated ITs thinking from YOUR thinking, IT will ramp up the FEELINGS side of ITs very limited powers. Getting YOU to FEEL what IT wants YOU to FEEL is ITS ONLY power left that can cause any knee-jerk-frustration in YOU. After the knee-jerk, YOU immediately know that FEELING is from IT, your BEAST.
Yes, those feelings will fade over time, and your recovery will then truly be in the past, as your former addiction is now in the past.
