He doesn't know me

I've been with Hayden for three years and engaged for two yet he still doesn't know me.
I was looking at Lego Harry potter for myself just as a dip in dip out kind of a game but decided against it. I don't have the time these days to brush my hair let alone play games.
Anyway he told me he brought me a gift which I received this morning. Not only is it not romantic nor my idea of a gift but it's nothing I've every shown an interest in. Sure he got me a Harry potter game but not the one I was looking at. I feel like he knows nothing about me and he doesn't try.
I'm just a little heartbroken.

Yeah I know I shouldn't be acting this way and just be grateful I got something but it's hurt me. This isn't the first time either. I have to write down what I want for Xmas or my birthday because no thought goes into it on his part.
I never thought I was hard to buy for but obviously I am.
Would it be insensitive to get rid of the game?

I'm going back to the doctors very soon. I've been diagnosed with depression but I'm convinced it's PND. The doctor dismissed it and said I couldn't possibly have it as I felt bonded with my son. However he's now nearly 14 months old and I still feel down in the dumps. I'm gonna request a different doctor I think.
