I feel like I'm fucking up my relationship?

My boyfriend and I we've been together for 7 months. Sometimes I text him cute little texts and he doesn't reply. Like tonight he said that he's tired and couldn't meet so after our phone call I left him a text "I feel you my little pumpkin, sending you a big kiss chilling at home it's the best" but he didn't reply. I don't know if I'm suffocating him with my love but I feel like expressing my love to him or when I miss him. He says that he loves that I'm caring and sweet. Am I overthinking this and potentially destroy my relationship? My friends think I should relax and not think about him all the time but I'm so in love that it hurts when we are separated. Don't want him to think that I don't trust his love for me just sometimes I wanna hear it more often or him calling me randomly to say i love you. Do you think i should text him again or call him and tell him that I need to hear that he loves me more often? I am feeling like I push him away. Tonight I'm going out with friends and I'm thinking to text him later "just want to say I got home, good night and sweet dreams" although he didn't reply to my texts. Mostly he's playing video games.
