He's thinking about it, considering it. Is this a dating profile? He likes or finds you interesting obviously but not sure yet if he wants to message you, and/or doesn't know what to say yet. Especially when most women don't even read and/or delete messages he can't just write anything.
anything to look at on your age? sometimes people just check to look at pictures or other things posted. there has been people I looked at their profiles but wouldn't message them. on dating sites its a bit weirder though as its so easy to message people and most singles send out many emails to random singles
