Subjunctive 4 - key

I'm afraid I've got some bad news. I know we agreed it was advisable that Stavros spend (1) the summer holidays with you. Unfortunately my parents have changed their minds and are now insisting he go/goes  (2) to Athens to stay with Aunt Sotiria. Suffice (3) it to say, they are not allowing any discussion! Athens it is, although he really wishes he could (4) at least share the period between you and his aunt. Dimos is going to England for the summer. If only life was/were  (5) so simple for all of us. 
Kind reqards,
