Long distance

So me and my boyfriend have just started being in a long distance relationship because he lives in another city 10 hours away. We see eachother at least twice a month but in the 2 past weeks, he hasn't really made an effort to text to see how I am or anything, or doesn't reply to my messages like he used to. We've gone from texting everyday to nothing. He has a full time job so I understand that he can't really text me during the day, and he has a daughter and I've always said when he has her every second weekend he doesn't have to text me because I know he's busy with her, but a good morning text or even one after work would be nice. Am I just overreacting? Really don't wanna seem clingy or naggy at all so I haven't mentioned anything to him. HELP 😢
