However, whenever in the descent motion of the squat, my groin feels really tight and is restricting my ability to comfortably go down past parallel. I've been stretching it out a lot but it hasn't seemed to help too much. So my question mainly has to do with my form and if it's possible that my feet are spread out too wide, which is causing this issue. My feet are slightly wider than shoulder-width with my toes pointed out at an angle.
It sounds like a flexibility issue. The wider your stance the greater the stretch (and overall involvement) of the adductors. For a while tight adductors were the limiting factor in my squat depth. A good stretch is asian squats. Do them with the stance width you normally squat, keep your lower-back tight and avoid getting into flexion as much as possible (this may be hard at first), and once in the bottom position use your elbows to push your knees out so you get a stretch on your adductors. You can also do what you see in this video
(time 1:05), go only as deep as you can maintain proper form at and use it as a stretch.
Origins is right in that squatting often will improve your "squatting flexibility". I don't agree with his comment about the toes at a 30° angle (slightly different angles work for different people and generally the wider your stance the wider your toe angle).
Assuming your form is otherwise proper, I would advocate going as deep as your flexibility will allow and don't sacrifice proper lower-back position for extra depth, even if you can't break parallel at the moment. If you work on this you should be able to reach proper depth soon (probably within a few weeks).
