Hi, Wanttobuff1! Welcome to the forum! I know you'll find support here. This group is awesome!
I think the best way to lose weight is to watch what and how much you're eating along with some type of exercise. Whether you use a
diet plan like Weight Watchers or just try it on your own, you still have to be conscious of what type of foods you're eating. Healthy food such as fruits and veggies really are better for you than chips and candy!

You also need to move! Get out and walk or jog or go to a
gym or whatever you like to do that will burn
calories. Doing these things consistently will help drop those
pounds.
Evidently your first wife was very insecure about her weight and maybe felt guilty for not losing more
pounds ... thus her anger over it. I'm sure it happens with alot of people, both men and women. Being overweight is a very sensitive area, and if one is angry with oneself for being overweight, that anger will be passed on to others. However, I'm very glad that you've found someone who is special to you again. Keep the lines of communication open. When the opportunity arises, tell her that you will like/love her no matter what her size, but that you will support her decisions on
weight loss like you hope she will support yours. Since you would like to drop some weight too, maybe you and she can work at it together. It always helped me to have a buddy to bounce ideas off of, exercise together, try new
recipes together, etc.
Good luck! Keep us posted on how things are going!
