Sorry for your struggles.
Your husband sounds like a good man. Believe it or not, many of us do care about your well-being, even if we don't know you in person. No one wants to see another person hurting. That's why we're all here to support you and everyone else.
That said, I'm glad you went to your mom's favorite restaurant. We did that a few days after my grandpa died -- his favorite restaurant. It hurt me a lot to do that, to go without him (since the only time we DID go was with him and that's it), but I know that he would've wanted us to be happy and celebrate his life. It would mean a lot to him, even though it upset me greatly. It sounds like you handled that tough time very well and I'm happy that it worked out for you.
