Not sure about your specific injury, but for those with complete anterior dislocation (typical-not sure about yours) the rates of re-dislocation strongly decrease in old farts. Meaning if your first dislocation occurs when you are over 50, on average you have a significantly lower probability of re-dislocation.

This is partly because old farts tend to do risky things less often, present company excluded, but also because we tend to be stiffer in general than those under 25.
Surgery is never a slam dunk, as people who have surgery can permanently lose motion and have residual pain, so some would suggest in the absence of complete rotator cuff tear seeing how much one can improve with rehab first prior to jumping into surgery. If rehab fails to return the control and stability the person desires, surgery could always be pursued at that time. Of course a lot depends on the extend and type of "new" tissue damage.....
PS: my older brother had a complete dislocation in his 40's that needed to be reduced in emergency department. No repeat dislocations or residual problems, and he regularly surfs, mountain bikes etc. He could afford to lose a few kgs though
