timewlker: 'There's sappers and there're saps!' (As me dear Grandma used to say)
I do sound like I've got a piece of straw in my mouth and a kangaroo strapped to the front of my ute with all this bush wisedom?! Yucko!
I don't reckon boo hoo Cho will be in the picture much in the future but Harry is meant to get a little more of the wet and wild, sucky facey in the next.
Will it be boo hoo Cho?
Will it be someone else?
If not boo hoo Cho, who? Hee hee- fun to say!!
A fanfic (on shnoogle.com),
explicitly 
depicted Draco as Harry's lover...???
(I know, I know!... but
I didn't suggest this, the fanfic writer did. OK! It
was an 'R' rated story so... I didn't have any choice
but to read it!!!? Anyway, it was really well written...
I only read such sites for the literary excellence you understand

.)
Anyway, I suggest you read it only because it gives some great ideas about what it's gonna be like for Harry to be a murderer/ a killer AND a lover; life after Voldemort.
