This is not a firm rule because the terms have no strict definition.You can only determine which term is appropriate by discussing it with the person you are seeing.
Relationships can involve many different degrees of actual relationship status, from the no strings attached relationship to the exclusively yours kind. He’s attentive (he texts and chats with me online every day), affectionate, asks me out regularly (we have seen each other multiple times every week since we met), and makes time for me (he has a lot of interests and activities).Our chemistry was immediate (physical, intellectual, and emotional) and things have been very easy so far. I am totally comfortable with the speed (how often we are communicating, seeing each other, and sharing information about ourselves).Exclusivity, when it comes to a boyfriend and girlfriend generally means that the two of you are dating exclusively, that means seeing no one else and attending most social events as a couple.This is probably the most common type of relationship status and can either lead to a long term commitment such as marriage or end in an ugly break-up! Well, if you are living together, then the chances are really good that you are way past the exclusivity threshold; that is of course unless you are living at the playboy mansion and Hugh Hefner asks you make yourself scarce for the evening.Many women would not even consider a partner to be exclusive unless they were officially engaged.
