I totally disagree with Dassie.
Of course you miss him, you had a great relationship and you feel you want to be close to him.
Do exactly as you have planned, go to your favourite place and talk to him. Also, say to yourself, - you know, he was such a wonderful person, -- wasn't I lucky that he was my husband? -- and wasn't I lucky that my son had him as a father, and although we didn't have as long as we would have liked, he has left a lot of very happy memories, of which I will be eternally grateful. Focus on the happy times and instead of them making you sad, be grateful that you found such a wonderful person, because not everyone does. I will be thinking of you. God bless.
