Gets engaged and he gets into trouble (6)
I believe the answer is:
meshes
'gets engaged' is the definition.
(I've seen this before)
'he gets into trouble' is the wordplay.
'gets into' indicates putting letters inside.
'trouble' becomes 'mess'.
'he' placed into 'mess' is 'MESHES'.
'and' is the link.
(Other definitions for meshes that I've seen before include "Co-ordinates" , "gets engaged" , "Fits into, intertwines" , "Interlockings, nets" , "Becomes entangled or fits together" .)
