Should I Return the rings?

I bought 2 diamond rings on sale at the department store. Both for unbelievable deals. I can afford to keep them since I am paying them off in 2 years with no finance charges. The problem is that I am OCD and can't seem to make decisions. I am struggling with whether I should return them and put the money towards other things. I am married with 3 kids. I am very stressed out and can't make decisions. It is debilitating. I have no one to ask. Should I keep the rings and be happy or return them for something in the future. No matter what I buy I feel guilty about. I am a returnaholic. Any advice is appreciated. Thanks.
