In favour of those who can spell?
Beginner Pilot, the only one who can answer your question is your wife. Is she prepared to look after your daughter single-handedly while you're away, is she prepared to cope with all the household chores while you are studying and flying etc? Same as all marriages, some survive and some don't; it's down to the two individuals involved.
Cheers
