<human>: Alright, here goes. 

My parents' marriage came to an abrupt halt over 2 years ago. Dad was getting erotic massages (this is relevant later) and got a porn addiction, dead bedroom, Mum had enough and found someone else, Dad found out. Shit hits the fan, etc. 

I now live with my mum and stepfather, brother and stepbrother. A couple of months ago, Mum approached me with some jewelry boxes and asked if I wanted them, since she didn't want them anymore. 

She explained to me that he would suddenly give jewelry to cover up the guilt he felt about getting a massage. I opened up the boxes and they're from a diamond store. A ring, bracelet, and necklace. Mum told me it's all worth about $5000, and if I didn't take it, she'd throw it away. 

They've been sitting in my drawer, and I feel torn. I can't wear it, not after knowing what they were bought for. I'm considering selling them, but the idea of taking all the money from it doesn't sit right with me, either. 

What the hell do I do with it? Do I talk to Mum and let her know my intentions? If I sell it, do I split the money, or am I okay taking it all?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Parents divorced, Mum gave me the jewelry Dad gave her when he felt guilty after getting erotic massages. Thinking of selling it, but feeling torn. What should I do?
