I don't like it when my brother keeps telling me he loves me

It just weirds me out. Even if he doesn't mean anything by that, it's just weird especially at his age of 50. I do all the work (I think) for taking care of my mom (when she was alive) and dad and he says lately how much he loves me and appreciates me for it and starts crying. The problem is that he used to tell me that if something happens to dad "today," that he can help me out financially and now he tells me that he needs to wait about 3 months before he "thinks" he can help me, money-wise.
