Help please

Hey ladies. My hubby and I are almost 5 years apart. He’s 26, I’m 30 almost 31. We have been together 4 years and married for 3 years in October. He was always so mature and always carried himself older. When we met I thought he was older than me !

We have been through some SHIIIIIITTTTT in our years together. Like he had a emotional affair last year and we went through me and my extreme anger issues because I was making him pay for my exes mistakes and I had baggage.. (much better now after anger management classes and counseling). We have 2 girls (6 and 6 months) my 6 year old is from a previous marriage. Well Lately it’s like he is aging backwards. He has gotten sooooo immature it’s like he’s a different person. We argue alot and I’m finding myself falling out of love. I feel like we are in a boring routine. He doesn’t make me feel beautiful anymore. I show him my appreciation with small things but he doesn’t anymore. I find myself thinking about the excitement of dating someone new and the freshness of it all. The butterflies of it all. I only

Daydream it though. I would leave before I would ever cheat on him. I love him... but I’m so lost on how to get our spiceyness back. And I want him to keep growing up instead of aging backwards 😩
