In need of relationship advice...

So I've been with my boyfriend for almost 3 months now, I know, not that long but I still need help with this "issue" I'm having..

I've known him for five years and we recently reconnected for some time and then we started dating..

Gradually as time traveled its normal route, i feel like his efforts have to some degree "depleted"

Hardly texts first anymore, hardly ever says that he loves me first (I don't want to say that he avoids eye contact when he does, but..idk) and sometimes it doesn't seem sincere or genuine?, it's very rare for him to call me, before we started dating, he would text me on a regular basis and even called a few times. And if I want to hang out, I usually have to say something...

I am officially confused...

He's a really good person and he's good to me, but..

I REALLY NEED HELP

This is kinda killing me. Am I overthinking it or expecting too much or what?
