Hi Stacy, my best recommendation is to get some professional instruction. Boyfriends/Husbands are terrible instructors...I know, my wife won't listen to me at all, even when the instructor suggests the same thing I suggested.
There are plenty of womens only courses available through the NRA or even local ranges. Just do a Google search, or ask at your local range. You should be able to get some instruction that way. In these classes, you'll learn proper stance and grip, and have a professional tell you how to shoot without hurting yourself. It's worth the modest fee.
