Sounds like pick up artistry bullshit. I wouldn't date either of you, pick up artistry to any degree however small is an instant deal breaker to me. I hate fake people.
I wouldn't like constant texting either. All day and night? Once we're together and both in love with each other,I'd want to spend as much time as I could with them. Now I understand some people need space no matter how much they love the other person, that's perfectly fine, but I'm not one of those people, I'm happy to be with a person who for the most part isn't like that and is on board with both of us spending all our free time with each other,even if we aren't always actually doing stuff together. But that still wouldn't involve constant texting. It involves spending as much time actually together with each other. If one of us is out and busy, there's no reason for us to text each other our every trivial act. I just look forward to coming home and being back together again.
To me, we are two parts of a whole, I'm happy that my relationship is at a stage where us being together feels the same as not being with other people. I'm as comfortable being with him as I am being totally by myself. It doesn't feel like it feels when you're with even a good friend. It feels like a complete lack of boundaries, but in a good way. In the same way as you don't have boundaries in relation to yourself, to your own body, he feels like an extension of that. Neither of us need to ask or feel they have consent to get close to the other. Because he feels like an extension of me and me of him. Two half's of a whole. To me that's what marriage is ultimately about.
Sorry to stray a little off topic, my point is, while I would not like to be texted day and night by someone I've only recently started a relationship with, that doesn't mean that amount of interaction is bad, just that form of interaction at that stage of the relationship can be bad.
