Can we love a person forever?

In less than 8 hours time, my mom will be flying off to Hainan Island..
In less than a week, my dear friend will be getting married to 'The One'

All if not most of my friends have stepped out in the working world, settled down with the right guy and/or planning to move on to the next phase of life.

For quite a significant period of time, I did not truly believe in relationships and love
Committment was like an obligation rather than anything else.
Over the Christmas last year, I officially got attached to my current boyfriend whom i met just over a month.
To him, it was like a 'click' factor.
To me, i probably still can't decipher properly.
To try to set things off right, i decided we should both be truthful to each other in all aspects, something which he agreed upon almost immediately
Since then, we had our squabbles and all
Times when he can really show his cold and harsh nature
Yet things was still alright.

Just slightly a week ago, i discovered my boyfriend was not that truthful
He dated another girl but had hid the fact
He had sent sms to seek for forgiveness to another girl
He had once just walked out of another person's life harshly
I was hurt
He explained. And we are still together.
Yet, still the pain is there, somewhere.

Did this relationship make a turn for the worst? I do not know.
Do i still like him? Yes
Is he still trustable? I do not know.

I've seen how so many guys can lie to their partners like it's not a big deal.
I've also told this to my boyfriend hoping it would not happen to me.
Yet, now i do not know.

Sometimes i realise it is me who is asking for too much
So much so that i can never be satisfied at the end of the day

In this week that my mom is away
I will be experiencing a true blue couple life with my boyfriend
Maybe then, i can make a proper & definite decision

Can we love a person forever?
A question left unanswered.
