Yes I tore mine and did not do the surgery.
I did PT for several months and worked very hard to stabilize the shoulder. At one point I could not even bench press the bar. Stick with the recovery. Seems forever at first. I think I did 6-12 months before it was finally really stable. I was having issues with sublexation (dislocation) for a bit.
The exercise that helped me the most was standing against a wall with a tennis ball and then touching the ball with your arm fully extended to the wall lightly. Pretend the wall has a large imaginary clock on it and start at the 12 and work your way around, touching the ball to each hour on the clock.
PT was painiful for the first few months. Pain meds wouldn't touch it.
I caught up on legs big time. Was in the gym on leg presses with a sling for month. Also learned to do no handed squats, but I am not suggesting this.
Good luck.
