Improve your safety - keep on training
Hello SMTP
I understand your concern - the girl friend has concerns after the events of the last few days.
I suggest that you :-
get your licence
learn from the mistakes/situations that other have found themselves in by talking to experienced pilots and reading accident reports (hide these from the wife)
continue your training - an hour with the CFI once a month doing various emergencies may leave you feeling inadequate (it does me !) but you will be a better pilot for it.
REMEMBER - when you are old and in a home sat there wetting yourself you will only have your memories so make them good ones !
Regards
Richard
