Really long post, I'd just quote afew lines.
I ask your pardon, TS. But I suspect you to be rather young; the
actions and maturity behind your actions are the root of my
suspicion.
I figured there would be a lot of "don't be sad, move on!", "just
follow your heart!" and "treasure your bf, don't stray!" replies,
so I shall not waste time patronising you.
Situation is more simple than it seems, I hope I'd be able to shed
some light.
(Forgive my seemingly harshness)
1) He has a gf; you have a bf. So what the fish?
2) "When i told him i cant msg him le... he say wana cry already"
Let me guess, he's 15
3) The real victims are his gf and your bf; have you considered how
they feel?
I guess the list goes on and it doesn't take a rocket scientist to
continue the list. I hope TS got enough wisdom/common sense to
understand commitment, faith and trust and how they work in a
relationship.
