Wannabe boyfriend's ambition so far? (2,4)

Ross

I believe the answer is:

to date

I'm a little stuck... Click here to teach me more about this clue!

'so far?' is the definition.
(I've seen this before)

'wannabe boyfriend's ambition' is the wordplay.
I cannot quite understand how this works, but
'boyfriend' could be 'date' (I've seen this in other clues) and 'date' is located in the answer.
The remaining letters 'to' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for to date that I've seen before include "Thus far" , "Up to the present time (2.4)" , "Reason suitor's come" , "Up to this time - check calendar" , "Up until today" .)
