Hi Kimosabe,
I think the problem lies in.....
The difference of maturity development level.
Your boyfriend,
Might be a little lagging behind.
(Esp since you said 'book out', so I assume he's a young man doing
NS. This is understandable)
If your BF was mature, he wouldn't do that, he wouldn't make you
feel uncomfortable by being too close with that other girl. It's
pretty common sense, isn't it?
He would've paid special attention and care, alarm bells should be
ringing in his head whenever this other confident girl was around,
and especially with you also being around at the same time.
He failed the test.
Again, this might not say about him as a person as a whole, but
could be just on this specific point, he showed he was not being
very mature. Or shall I say, socially inexperienced/ low EQ.
Don't blame yourself and taking the problem into an internalized
problem, like this is a problem with your emotions.
There is nothing wrong with your emotions.
There would be something wrong if you didn't feel this way.
You just reacted to a cause. You can modify your reactions to it,
but then, you should ask yourself whether you should instead modify
the cause. Which is, in this case, your boyfriend being not
sensitive enough.
I would recommend for option two, modify the cause. I think you
have a valid complain, there is a stronger case to modify the cause
compared to modifying your reactions.
So,
Why not you talk to your BF and make him understand.
I think he will.
If not.......then see how...it's up to you whether you want to
continue in such relationship where communication is difficult.
