Boyfriend trouble...🙄😞

Basically I've just gotten back w/ my ex and he's suddenly just blocked me on everything he's done this before because his mum found out we fucked and he is 17 and turning 18 February and I was 15 he says he's in love with me but I don't know what to do I love him to bits and can't get over him I wish I could just meet and talk to him.....what should I do?
