Relationship advice

So I’m currently in a relationship and I love him so much. However he’s not like any of my past boyfriends who would show that they love me and text me cute paragraphs, he just doesn’t do that. He doesn’t complement me about my looks or do anything to hype me up. He says that he wants me to have his kids one day and talks about marriage but idk if this is how he is in relationships like he’s just not affectionate or what. I personally like to be complemented because I am very insecure about myself and I just feel like I’m not wanted because he doesn’t do any of that stuff. Do u guys have any suggestions?
