Where do you see your relationship with his mother going? How many other partners has she lived with between dad and you and what were her previous living arrangements when not with a partner? History helps.

Also, pick your battles. "Daily" disciplining seems like you may be coming down hard. Pick the behaviour that bothers you most, explain to him why it's wrong and what will be the consequence of the behaviour and then follow through. Try to find acceptable compromises. Is he sneaking candy (many kids do this, btw). Either don't have candy in the house or maybe decide that it's fine for him to have candy as long as he checks that it isn't just before dinner and he brushes his teeth afterwards, for example. Hopefully the behaviour will lose some of it's appeal.
