watching,
im commenting based on your very first posting because as the thread stretched into an epic debate i lost touch with the arguments.
perhaps you are not really paranoid or insecure. perhaps the root cause is that you are in a relationship that brings out the worst in you.
if your SO were a true gentleman who does not openly oggle at girls, it would not stir up the feelings of insecurity in you. i also suspect that your SO is a little bit of a devil's advocate. why on earth should he tell you about a PRC woman centering her attention on him, other than to provoke jealousy in you. seriously, i dont think it is as simple as he being such a docile boy that he reports everything to you. he could be subtlely trying to trigger off something in you, which could be attention, jealousy, etc.
(actually i have other thoughts on the PRC girl. some females like to centre their attention on men out of habit. they were conditioned since young to cosy up to men whom they hope could extend more help and concern to them, compared to female friends. it could just be a habit with no further motive)
so why is this relationship so combative? yes, this is the word i use - combative. you present your arguments versus his arguments, as if struggling over who is right or wrong. the reader even gets the impression that you guys like to threaten each other. if you started out being a person who has a strong desire to be in the right, such a relationship would make you more competitive and self-righteous.
do you realise that other people's relationships are not like that? do you realise that it is possible to happily live and let live, give and receive and manage a relationship with peaceful consensus?
as a woman, i do not like to feel that im in a constant state of hostility or readiness for war. being in such a relationship does not make me feel appreciated or at the most basic level -it makes me feel unwomanly.
despite your aggressive opinions and strong posturing (the impression shaped by your first post) you seem to want to possess him badly. to me, this is ironic. how could you ever own a person's heart if you are not even able to trust him fully? by analysing things to death? by arguing or threatening? all these is futile, like trying to box your own shadow.
i think all this boils down to is a very real trust issue in your relationship. i have male friends who are married who go out with me on a one-to-one basis, and their wives are totally cool with it. at first, i thought that they might be interested in me or something, but as the years go by, it is obvious that our friendship is platonic. so what my male friends have with their wives is called TRUST. they go out with female friends one-to-one, their wives trust them, and they do not break their wives' trust.
why can't it be the same for you as well?
if he really ran away with this PRC girl after just one date with her, or if this thing grew out of hand, this would prove that whatever he had with you in the first place was not genuine love to start with, am i right? in this case, wouldn't it be better for you to know earlier than later?
personally, if i were you, i would be very disappointed to see his reaction afterwards - the being disgruntled and all that. this indicates that he could be a closet flirt with unfulfilled desires to meet other girls. why isn't he happy to have made a decision that should have pleased you? but i do not have enough info to be the judge on this, you decide if there is any truth in this.
