It really hurts when your man doesn't appreciate a gift that you've put all of yourself and your effort into.
I'd know. I proposed to my bf on his birthday, giving him the wedding rings. He later says it hardly counted as a present because it was for US, not HIM. It felt like he ripped my heart out and stomped on it.
Yeah, I'm still marrying the bastard.
(I love you honey)
But with your situation, there is no making you feel better. All I can say is that I feel your pain and I'm sorry. The damage is done, but lesson learned. Never buy a man any type of electronics unless you've heard him specifically say what he wants. Usually they WILL be disappointed because they already know what they want, and you may have gotten them something completely unrelated to the system that they are working to build.
