Wife Thinks I’m too Fat

I’m M42. I have been at least a little overweight most of my life. Married my wife also 42, twenty years ago. For most of that time we were both overweight with mutually poor eating habits.

After having children 10 years ago she started taking care of herself. Subtle changes at first…but more and more over the years.

We both work, and share much of the children duties. Though I often fill in while she is out.

Several times she has asked me to put more effort into exercise. She says it’s because we are both getting older and health will catch up to us soon…but I think she just wants better looking husband.

Lately she has taken to reminding me about her changes more often, and pleading with me to do something about my unhealthy habits. I’m annoyed that she won’t let this go.

I don’t like exercise and I do not want to do it. So what if it’s unhealthy. It’s my life.

AITA?
