Trust

In a relationship, there must always be trust lying somewhere.
Even though this trust can often be breached and often been misplaced,
at the end of the day, you have got to trust your loved ones.
Deep in my heart, something that happened in the past will always come back to haunt you.
Even though the incidents are not the same, it does strike some similiarities and causes an impact on me.

Just like what happened to me on my ex gf, similar issues of trust happens.
Am i so gullible?
Am i over-reacting?
Am i thinking too much as i always am ?
Am i falling into the same mistake i have made years ago ?
Why isit that i have not learnt my lesson about trust.
