I've been struggling with a pulled adductor for 5 solid months. I pulled it while doing lunges -- I thought I had been focusing too much on squats and it was time to do some single-leg work so that in the future I would avoid injury...
I did not think I tore it badly, but it is still problematic. It didn't help that I continued to train hamstrings for several weeks. Adductors and hamstrings work together, so I wasn't resting it.
According to several studies, adductor strains take an abnormally long time to heal. Google it and you'll find rehab protocols and studies.
For the last month and a half I have been getting ART, with mixed results so far. Three steps ahead and two back, it seems.
