How do I know when it's time to maintain?

I'm 5'8, 34 years old and started out weighing 181.  I currently weigh 145.8 lbs.  My original goal when I started was 145.  I see a lot of other women my height posting that they are aiming for the 120's or 130's.  I just saw that 145 was right in the middle of a healthy BMI for me so I picked it.  Does anyone have any suggestions on a good weight for me?  My after picture that I have up now was taken at 148 lbs.
