He hasn't texted in 3 days but used to text constantly, should I be worried? One of the last things he said was that it feels like it's been forever?

Known him for a little over a month, seen each other about 7 times ( usually 1-2 times a week ) and a good morning text everyday along with asking how my day is going, and goodnight.

He was busy with work so we haven't seen eachother in 2 weeks and in that time he has said he's tired from work but also that it feels likee It's been forever since he has seen me (been 2 weeks) and he wants to watch a show we like together soon. Problem is, it's been almost 3 days since I heard from him. He's the busier one and I was the person initiating the texts before he went quiet and so I don't wanna be annoying/needy/bothersome if he's busy, but I'm also feeling like the fact that we haven't seen eachother and not texting for 3 days is slowing the progress of dating. Has he lost interest? Should I text him, if so, what? Should I give him his space and just wait? What he said in the texts right before the 3 days showed that he missed me (I think) so did he suddenly change his mind?
