Unappreciated

Does anyone else feel like their SO doesn’t really appreciate them, is it normal/common?

We are young 24 years old, but have been together for 7 years with 2 kids. I’m realizing I have put myself on the back burner, putting him first. All his wants and needs.. with being hardly appreciated. Idk I just want to start putting myself first a little bit more but I don’t know how to. I love my SO very much, but 7 years is along time to be putting myself last or is that just what I’m required to do now that I’m married? Lol someone tell me I’m not crazy that what I’m feeling is normal, and something I can work on.
