My decision was as follows.
Since N already showed 7+♥, and S, presumably, also 7+♠, I had 3♠, then my partner should be very short in ♠, and at the same time, he should be very long in both ♦ and ♣.

Hi delmo, You applied some logic (3 level pre-empts are often 6 cards long these days though) but you missed the point.

Your first double asked for partners cooperation and when they didn't your 5♦ bid was flying solo. One disaster such as the opponents going down in game and/or extracting the max penalty and your partner has every reason to be VERY upset and definitely begin underbidding out of fear, trashing many future results.

I often quote Allan Graves from an old bidding contest: I don't mind a poorish result to maintain partnership bidding integrity.

I will point out that if somehow you think that you must try to play in a minor at the 5 level, bidding 4NT rather than 5♦ should ask PD to pick his best minor in this type of auction.

Indeed, but if anyone should do so, it is west who should bid 4NT over 4♠.

I agree with this comment. Yes, it's West who should bid 4NT, since E already showed an opening value by doubling the 3♥ bidding by N.

The first part of the comment though was IF anyone should do so...

PS you are very polite but you don't have to thank people for advice s frequently! Don't forget that it bumps the thread.
