Looking for advice. I am now in my 40s and my DH and I made a mutual friend at Uni. He didn’t pass his degree, has struggled to hold down work and a relationship. Let him live with us for a while on mates rates, and just got used to buying an extra pint or an extra meal. All good. Was genuinely a nice fun person to be around in our 20s. However the years have passed and it’s all got a bit dark and twisty - the student mistakes (not revising, no commitment to work) have been replaced with a new darker set, drink driving, drugs, adultery. We have had enough and want to walk away. The problem is that our mutual friends think we are being judgy and mean for ‘giving up on him’ and it certainly has a big impact on our social circle. We don’t want the responsibility of this and it’s not in line with our values. What would you do?
