Pseudomonas … to treat or not ?

I was diagnosed with Pseudomonas and Bronchiestasis 2 years ago. At the time my dr treated me with 3 weeks of Levaquin without follow up sputum. It was diagnosed with a bronchoscopy. I now have a BE specialist and he says there’s no reason to treat it because it has colonized and will always be there. My cultures show heavy growth. Thoughts on treating or not treating ?.
