Not sure what you mean by "does not rely on blank lines in the source
text", but the following technique inserts a consecutively numbered
blank line (and, technically speaking, is not a blank line in the
source text):


.nm 1
This is line number 1
.br
\&
.br
This is line number 3


(You do need the "\&"; if you delete it so that there is simply
a blank line in input, you get a blank line in output but the
numbering is skipped).

You could wrap the above in a macro:

.de nbl
.br
\&
.br
..
.blm
.nm 1
This is line number 1
.nbl
This is line number 3
