I think that it might be a good idea to be more explicit with your t about what is upsetting you. It seems like him forgetting things is the biggest issue for you at the moment - and I would be so, so upset if my t forgot such important things. But I agree with the others that in the email you put nearly all the blame on yourself for how things are going and you only made a brief reference to him forgetting things. I think the reason he probably didn't apologise is because he didn't realise how upset you are about him forgetting the email. You made most of the email about other things and he responded to that. It's okay to be hurt, angry, disappointed, sad, however you feel and let him know this. It sounds like he wants to be there for you so I don't think you'll lose him by being more open about how you feel. I know I couldn't get anything productive done with my t if she was forgetting important things. I hope you can email him/see him and tell him point blank how you feel. Maybe send him your posts from this thread?

I'm sorry for the loss of your dog.
