Basically, no.
You say that you were never visual with the 737 so , as long as it was safe for me to make the turn requested of me, I'd make the turn. And I would have thanked the ATCO as well. One thing that isn't often said here, is that if you can help another person, then the favour, usually, is returned.
If the 737 had had to move out of your way they'd have filed a report giving the ATCO a hard time for not keeping the required separation. The next person to upset them will be given a real roasting.
