Husband feeling insecure after my weight loss and minor makeover?

Sooo I had a baby 10 months ago.. I’ve just lost not even all of the baby weight but some and am starting to fit into normal clothes. I’m 35 and have had 2 children., I’m stressed and noticing over the years of being a mom and the weight gain and aging has caused me to look a little different.. so I’ve taken some minor steps like getting Botox, extensions getting my hair fixed, and buying some new clothes. I also did get lip injections a very small dose.. you can barely even tell,. And a while ago I got my teeth fixed with veneers, last year. Something has happened where he sees this improvements to be threatening to him.. never a babe you look beautiful I’m so lucky to have a beautiful wife.. no but instead it’s like “who are you trying to impress” “why are you doing these things” “is there something going on I should know about” … just so so so insecure.. I do not understand it and it’s making me so sad! Why can’t he just see it as a fun thing I’m doing to make myself feel beautiful… what do I do? The nagging and mean jokes have been going on for months and I feel like it’s getting worse.. it’s driving is apart and that makes me sad. He’s the love of my life! These things are to feel good about myself and hopefully make him more attracted to me,.. it’s backfiring. Any advice ? Do I make myself more unattractive to like make him feel secure again?
