It may have been illegal in Florida to tape you without your consent: Florida is what's called a "two-party consent" state (though that really should be "all party consent" state) and that means that a phone call may not be recorded unless everyone who is a party to the call consents (or unless there as court order--i.e. a warrant). The prosecutor is allowed to try to get you say things helpful to your case--to "bait" you, as you say--but recording the conversation may be improper and if the conversation were to be used against you or your boyfriend, it may be possible to get the conversation excluded on that basis.
