Hi there , Actually It depends. sometimes you must use the first and sometimes you must the second example for "to me" "Hello my son , I'm really sorry for the argument we had last night.Come tome. Dad loves you." example for " for me" : "I have some problems with my homework , so I think this book is good for me and cane help me a lot" . . I hope this answer will be useful for you. sincerely Alireza.

Without any context, I'd just add we normally use 'to me' when expressing a personal opinion, but I'm afraid this would also be an incomplete explanation since it really depends on the context. For instance, we can say 'It sounds good to me', but also, 'As for me, I like how it sounds'.

we actually need more context. But for me = for you to use or own. and "to me" = to be given to you brought to you. although there is overlap in the usage that's why we need the full sentence or context.
