Hopeful - Hun you really need to take some time to grieve (I don't think you have done that properly yet) this is not something you can get over easily, take some time talk when you want to, have quiet times when you want to
I have never lost a lover (so I can only empathise with you hun). When my Father died I wanted something special to remember him by so I made what I called my "box of memories" these memories are for my eyes only.
In this box is all the condolences cards, his comb, photographs, an empty wallet, his medals, a hanky (he never went anywhere without a hanky
etc things that are personal to him) Whenever I am feeling sad I just get out my box of memories and that helps me and all the good times come flooding back.
As for your little girl hun (she's probably just being a little girl) it's you whose emotions are seeing things differently. When I was going through my m/c both the first and the second time my boys seemed to be total little buggers I found myself shouting at them and getting cross with them shortly followed by lots of hugs and sorrys (It's a confusing time for children too hun)
If you feel strong enough to sit around and talk about the love of your life with his family - do it. If not just tell them its a little bit hard and your emotions are raw, also ask how they are coping (everyone has different coping strategies).
I also have planted a tree in honour of my dad and I now have two plastic windmills beside it (maybe if you could do that or place a stone somewhere nice with his name on it) somewhere you both went?
Making a shrine (for me personally) has never been an option as it would be far to upsetting to see my father's face every time I walked into a room. The candle and balloons is however a lovely idea and I'm sure he will appreciate it too. I light a candle for my dad on special days.
Sorry if you feel I have overstepped the mark hun, this is only what I did and only you know what you are feeling, I really hope you can work through your pain and suffering hun and the ladies here I am sure will support you every step of the way.
