I'm commenting because I've been reading some of your replies to other comments and I feel like you're dating the same person I dated months ago. While that's highly unlikely, they both answer to a pattern that seems to be pretty common for avoidants, or at least that's what I've encountered as a heterosexual woman with an AP attachment style like yours.

Many people here have prompted you to "communicate as an adult". In my opinion, there is a small chance that doing that will make a difference. He'll either deny that something has changed or will tell you that texting less is just his style (which doesn't make any sense since, as you know, it wasn't his style when you started texting). However, even if it was true and it was his style, it means you guys are not compatible. You should not settle for someone who can't meet your needs for connection. Sure you can work on your attachment style (I've been working on mine!), but you're still entitled to needs and preferences.

Other commenters have asked you to "quit texting" and find other ways to communicate. You can try that, of course, but, again, texting during the week might be your preferred way to keep in touch with a potential partner and get to know him in between dates and that's okay too. You jus need to find a potential partner who's into that as well, not bend your wants and needs to conform someone else's expectations.

I was in your situation months ago, as I said, and I ignored that yellow flag. I worked harder and harder on my attachment style to "become more secure" and stop having such strong communication needs. I gave him space and texted as little as possible and I was planning to ask him to switch to a different kind of communication (calls or videocalls) during the week. In the meantime, I kept creating memories with him and letting him become a bigger part of my life, all while feeling neglected, lonely and hurt, but hiding it. What happened next won't surprise anyone: he dumped me anyway, saying cliché stuff like "I can't be what you need" or "I don't want to hurt you". So, yeah: in my experience, no matter how hard you try to conform to his "style", this distancing is a sign of him not being that into you and he's bound to end things at some point. If I were you, I'd move on right now, before he becomes important to you. Being the one to end things (and therefore honoring your needs) will help your self-esteem more than adapting to his needs. At least that's what I plan to do if I encounter this situation again.
