My H's ex is encouraging his older teenage children to come to us BUT we are in isolation due to my H's underlying health issues and mine . We are therefore seeing no one . This is week 3 for us . We are both about 10 years older than her . However his teens have been out to supermarkets for food for their Mum. If they come to stay with us then what has been the point of our isolation ? Am I wrong in saying that they cannot come to us ?
