請各位大大幫幫手,我想知下邊里句英文係咩.

我這一輩子都會好錫你
in my opnion, you should write it in this way
'''I promise to love you forever.'''

we seldom use
''i will love you....'' for 會好錫你 since it is a bit strange.
usually a man will say this sentence when he is having a courtship with a woman
so he will promise to love her

we also seldom use
'''I promise to love you in my whole life'''
the man loves the girl, so i think he will love the woman for a long long long time.
so '''forever''' is better than ''in my whole life''

I would cherish you the whole life long.

I will treasure you for life.

I will love you dearly forever, till death do us part.

My life (in love with you) is good enough.

i think :i will love u forever ? (maybe)
