Is this sentence correct?

[rainous]

Since I loved him enough to marry him, I worked ceaselessly for the next 15 years, hoping that he would some day clean up his act if I stuck by him and supported him.

Hi,

Firstly, I would like to know how the sentence reads for the natives.

Also, as to the underlined phrase, I wonder if it's OK to omit the first "him".

Or!!!

Is the whole "and supported him" unnecessary?

Thanks in advance.

It's possible, though I would write 'Since I had loved him ..'

Also, as to the underlined phrase, I wonder if it's OK to omit the first "him"
It's possible, but awkward, in my opinion..

Is the whole "and supported him" unnecessary?
I don't think so.
