Hi Julia Thinking of you. Him not sending a note with the from has nothing to do with you - and everything to do with his own guilt and not being mature enough to deal with the situation.
Are you likely to be talked into something that isnt good for you financially when you meet up with H? If so I really recommend asking someone (preferably male older family member) to be with you for this catch up with H. More awkward with a third person there, but good to be prepared for the absolute worst and to have someone else looking after your interests.
P.S Stay away from lovely men with cute NZ accents! I married one! (Although surely they cant all be bad!) If you come as far as NZ you have to come and visit me!
