i believe it's not what u do now that matters. it's how u feel.
if this thing is gonna nag at u even if u confront him or not, then
wat's the point? it's about how u are gonna get urself to trust
him, and have no worries about him flirting. he can even be
flirting in front of u and u wouldn't be affected. of course i'm
not saying that this is wat he should do. it about how u decide to
view the situation. sometimes, i understand, it's hard to control
how u feel.
out of topic abit. just wanna talk about such situations. there is
one "rule" that comes to my head. "what you don't know can't hurt
you". maybe this passage i'm about to type refers to ur bf, for
this case. he, stupidly flirts with a girl online and LEAVES proof,
and now he should suffer the consequences. had he not left a
history behind, none of this would have happened. i believe (since
u do) he treats you like his princess and wouldn't dream of
betraying u in real life, but why throw a spanner in the works by
letting u find out something like this which was done in the name
of fun or even boredom? to all of u reading out there, the
statement of "what you don't know can't hurt u" refers to all the
things that u do that could LEAD to ur other half finding out and
being unhappy about, even if it's done without any harmful intent
whatsoever.
the reason why i feel this is important in a reln is becos
sometimes it's not what we DO that bothers the other person, it's
what they BELIEVE. just an obvious example, if i came home one day
and caught my gf in bed (clothed) with another guy, and she says
they were just lying there tokking cock, u think i'm gonna BELIEVE
that even if what she said is the truth? (pls don't say it's her
brother or cousin or wat. even my BEST friend wouldn't or shouldn't
be lying in MY bed with MY gf rite?)
anyway back to the topic, let's really hope that ur guy is a good
man, and that u get over this apprehension of urs quick smart.
whatever u do (confront or not) isn't wrong, it's just how you
decide to deal with it. i wrote this in effort to bring up a point,
which is not what he did, but what u believe, what u think is
happening. if u truly believe in this reln, then try ur best to get
rid of all those negative thoughts. confronting him may help, it
may not. u know better.
hope things get better soon!
