Does anyone find ot believable that the Platrow character wiuld be married to the Douglas...

I'd have to see it again. The actors are 28 years apart in age, and that's a lot. I don't think there is any explanation as to how they got together. But to dwell on it would be a distraction, and it certainly validates her desire to take on a handsome young lover. As someone said elsewhere, it's a very handsome and well made movie. Hard not to think of Unfaithful at the same time.

I never thought it realistic at all. It's like she married Gordon Gecko! Now, it would be more realistic if he was the one with a billion dollar trust fund and had a young, trophy wife.

I actally found it less believable that a woman would cheat on Michael Douglas.

His real life wife, Catherine Zeta Jones, is only three years older than Gwyneth Paltrow, so I guess it can happen.

Not really, not by what is presented in the film. However, there relationship could have been different in the beginning. I don't think it says how long they have been married or how they got together. Maybe he didn't become so possessive until after they were married, had her money, and built up his company. She does she kind of flighty though. Maybe he was the hot thing that she wanted at the time just like the painter guy.

Yes.

But I also could never see DOUGLAS killing the mistress on a train!

Yes.

He was capable of putting an act on.

Or maybe, initially, he did sincerely care for her.

Perhaps, more likely, he had a long term agenda from day 1 (he knew full well what he was marrying into).

What is unbelievable is not so much Paltrow's character, but her family, allowing a marriage with no pre-nup. This would never happen.
