Well, let's see. That was pretty good. You're getting better. Good for you. I see you as a very passive person, who is deeply in love with your wife.
I see your wife as a person who, having lost 100 pounds has found a new person inside of all that extra baggage that she was carrying around. How long did she carry that weight? Did you encourage her, or buy her pretty clothes or presents while/after she was losing the weight? If not, perhaps now is the time to let her know you NOTICED. I don't know what you've done for her in that department. Perhaps you've already tried to let her know you appreciate the weight loss.
Also, are you overweight as well? If so, have you considered going on a diet too. Maybe you could ask your wife to "help" you since she had such great success. Sometimes, things like that will bring two people closer together. Yes, I know it is hard to do. And, yes, I'll bet you've been trying, but maybe trying a different approach will work better. There is a great diet out there, called South Beach Diet. You could rent the book from the library and read it through.
I could be totally offbase here, but give it a shot. If I'm wrong, please tell me so.
I'm going to bed now, so I'll check on you tomorrow. Keep talking to me Craig.
