How long have you been dating this guy?
All sounds normal to me. BTW I have an email account that has 21k messages LOL.
There is exception here though I agree with refiner. The dating website is odd to me - not that its up but that he keeps checking it.
You sound committed and uninterested in dating others. One can be exclusive with someone and not commit to marriage or engagement just being exclusive. Address it with him if you think its been long enough to wonder why he is still on it (and you must since you brought it up) I always thought that saying one was exclusively sexual with someone, but not exclusively dating to be odd. Why give the milk without buying the cow? No, not talking about a marriage or engagement. Seems you have one foot in and one foot out when you don't commit to exclusively seeing each other and commit to exclusive sexually.
