How to capture the rest of a sentence after one or two matching groups with regex?

So i have two sentences that I'm working with and I'm interested in making specific capture groups based on the characters in a word. So i have these two spanish sentences:

Yo quiero irme de viaje.
Yo puedo caminar en la nieve.

The first capture group has to be one of the verbs ie. "quiero" and "puedo" so i do that with this regex ([PpDdQq].*o).
The second capture group has to be a word following directly after the verb, ending in "me" and I do that with (\w*me).
Now for the last capture group,it has to be all words and blankspaces following directly after the first capture group in the absence of a direct word ending in "-me" or all words and blankspaces following directly after the second capture group in the presence of a direct word ending in "-me", I used (\w.+) but it didn't work.

Could anybody help me figure out why? Thanks. Below is the full regex and link to regex website containing the expression and examples to be matched:

([PpDdQq].*o) |(\w*me)|(\w.+)

Solution

Use

\b([PpDdQq]\w*o)(?:\s+(\w*me))?\b(.*)

See regex proof.
