I have been in a relationship since Jan 1st. The gentleman I am involved with says we are seeing each other rather than dating... what is the difference?

It all depends on the person, but to me it sounds like he is still keeping his options open, and or/ isn't ready for a real relationship with you. Is it possible that he is seeing someone else?

Seeing each other and dating are the same thing. But he has discovered some women think "dating" is an exclusive endeavor, you know that it's not.

Until you officially ask her to be your exclusive girlfriend/fiance, you really CAN date anyone you wish. But women will frequently respond badly to that, even if you haven't become exclusive yet. Unfair? Yes. But common.

Just keep that in mind.

Dating and seeing someone is the same thing and its for having fun while you get to know each other and decide to take it to the next level, exclusive dating. There are no commitments of being exclusive while dating or "seeing someone". So have fun and see where it goes, remember you are as free as he is.
