After reviewing some chatting sites, some women talk about men not texting as much as they did earlier on in the relationship. I think that is a good thing and it may mean your relationship has developed into more face-to-face contact and voice calls.
The danger is when texting is the main communication because that could be a signal for:
1. false intentions
2. having you hanging but waiting for someone better
3. wrong kind of guy
Technology is not meant to make it easier for guys to treat women in an inappropriate way. So ladies, if the signs are clear then delete the contact.
