Some good stuff being said here, as usual. I wouldn't look at the lack of texting as a bad thing, personally I see it as a positive. After my small toe dipping into dating I realized anything I wanted in the future wouldn't involve heavy texting. I enjoy my independence too much and have too much going on to be that involved in my phone. If I text with someone too much it also takes away the excitement of getting to know them in person, which I prefer. I get it can feel like a precursor to them not being interested, but try to flip the script in your head and realize that's not the only meaning, sometimes it's just them feeling things out and living their life. Give him time and let things play out naturally. there's no rush to this
Accept what is, let go of what was, and have faith in what will be
