My oldest friend who I've known for 22 years hasn't been great at staying in touch since moving to another European country - but usually we catch up every one to two months on everything and usually go on trips with mutual friends each year.
Anyway, I had a mental health crisis three months ago. I had multiple bereavements within weeks of each other and other difficult circumstances which lead to a breakdown. This friend was great for a few days, helping me find my strength and a general shoulder to cry on. Since then, I've been in therapy and slowly getting better.
But three months on I've heard nothing from him. AIBU to have thought he would check in at least once? I'm quite hurt by it. I know he's been on holidays etc so he's alive and kicking
