I know that it must make such a lovely change after everything you have been through to have a man treat you like a princess. I think your friend is just voicing words of caution. You have been through a hell of a lot, it might be wise to go for the counselling and spend a bit of time by yourself, re-adjusting and getting to know yourself again, without anyone else being around.
I'm not saying don't date this guy and have fun. But perhaps keeping it as a friendship at this stage is wise. If he cares for you, he will understand that after such a traumatic year you will need a bit of time and space. It's necessary to come to terms with what has happened. But when all is said and done, you know yourself best and only you can know if this feels right or not.
I am truly delighted for you that you have found someone who seems like a really nice person. But at the same time I cautiously sympathise with your friend. I don't think you will rush into this, but I do hope that you are spending enough time on your own too.
