Your best bet is to turn off cellular data so you are just using the wifi. Then, use iMessage to connect with your boyfriend. The only downside to this is he will only be able to connect via iMessage when you are connected to the wifi. If not, and his phone is set for Send as SMS if imessage fails, then his message would be sent as an SMS. You would receive a text if you do not have the device in Airplane mode, and this would be an international text and have a cost associated with it.

Email: Go to Settings/mail,contacts, calendar and tap on each email account, then turn it off. Note that this will delete any existing messages on the phone. If the account is POP3 they will be gone forever. If it is IMAP or MS Exchange they will be restored when you turn the accounts back on.
Text: If your boyfriend has an iPhone you can use iMessage over WiFi. Just turn it on in Settings on both phones. If not you need some other messaging app such as WhatsApp, Viber, Yahoo Messenger or Skype.
Cellular data: Turn it off in Settings/General/Cellular, as @Two3s suggests. If you do this you don't have to turn off email, as email will only be retrieved over WiFi, but if you really don't want to receive email anyway turn it off as described.

1. Settings > Messages > iMessage > ON for both phones (if you haven't already)
2. When you leave for Aruba: Settings > Airplane mode > ON, then Settings WiFi > On and connect to your free WiFi
3. You can now iMessage each other without needing any apps, at no charge.
4. Since you have free WiFi, and your cell network connection is disabled by Airplane mode, you can email. surf, and use internet accessing apps without charge.
