A strong, confident man would be happy someone else improved themselves. Your W has lost weight, improved her health and is improving her self-esteem and self-confidence. But instead you are jealous and angry because you are stuck.
Your W would never tell you that she is moving on. She knows you can't handle it. She's tired of that. It's unattractive and boring.
