How do I go about this

Started dating this guy for about two months.

Sometimes he’s really into the conversations, other it seems like I’m bugging, which is an ugly feeling.

Since we’re only dating I just kind of go MIA I just stop replying because he seems uninterested. What would you do?

I don’t want to tell him how I feel because we’re only dating

But I don’t really now how to go about it

Edit- I stop replying and he writes to me later, it just seems like I always try to keep the conversation alive. Like if I don’t do it there’s nothing there.

It’s kind of boring.
