This situation is pretty bad, it's important to remember how this made you feel. That was something you did out of love and consideration for her, if she can't recognize that and appreciate it, it maybe time to find someone who does.
I've had a SO say they bought games for me, not even let me play them because it was on their console, and I couldn't react that way. Gratitude has a place in love.
I just hope this works out in a way that you can be happy, whether you work things out or find someone more receptive to you being thoughtful
