Should I just leave it be?

So every morning my boyfriend and I usually text “Good morning I love you.” If I don’t do it, he usually does.. But I mostly do it most of the time.. But this morning I didn’t do it because I just off from work and I was tired. But he knows that so he does it sometimes. But when I woke up around 3 in the afternoon today I realized he hasn’t texted me at all. I know he is at home and not doing anything because he just had surgery two months ago and he can’t really walk right now. I didn’t know what was going on because it’s not like him to not say anything to me because it’s already been half of the day. Now I’m thinking is he cheating because I’m already in school and working at the same time. So he might feel like she doesn’t have time me etc. But before I got in school he said that he understood and he will support me until I get my degree. But when I texted him first around 3:30 I said “hey” and he sent the waving hand emoji “👋🏾.” Maybe I’m just taking this too far but at the same time I felt like something wasn’t right. Maybe I’m just being paranoid about him cheating... I want to talk to him about it but at the same time I feel like maybe I should see how the next couple of days will go and then talk to him about it if it continues the next couple of days...
