Is it normal to tell him exactly how i feel and its okay?

Apparently, guys need to be told directly and verbally about everything especially my bf it seems. He comes off as really clueless and emotionally immature. I literally have no idea what to do about it anymore. First, I stood up for myself like I always did but that just chased him away and turned him off so then I learned to accept the way he is because thats what he told me to do is to accept him and take him the way he is. It has lasted longer than I thought but Im starting to just want to stand up for myself again. I feel like accepting him is just letting him walking all over me. So now Im standing up for myself again and letting him know when something is wrong. I want to know why is it such a turn off for guys when girls are standing up for themselves? why does it come off as nagging? Yeah some girls are straight up nagging but its rude when guys point out its nagging when its just a girl standing up for herself. Its kind of like the guy has no balls to face confrontation.

So then I found out something new to do and that is to just tell him verbally on how I feel for him so basically tell him how much I appreciate him and love him and how much he means to me. Is this going to work? dont guys get scared when girls confess their feelings to them? even though thats another thing guys dont have the balls for is to take it and appreciate it but no they have to get "scared" because its "commitment" and theyre about to lose their "freedom" so they have to take it slow. Honestly, guys are babies. Why do they get so scared of commitment? Its just so weird and not that big of a deal like relax, you might get your freedom back so you can be free to get with any girl and mess up as much as you want.
