He cheated. Should I fuck his shit up?

I’m 36 weeks pregnant and found out my partner cheated on me. Hes asleep right now at mine. But I have his phone, card, car keys and house keys. (We don’t live together.)

I want to throw all his stuff in a bin somewhere he’ll never find it. Don’t come for me saying it’s childish or illegal. He literally cheated on me last night, god knows how long it’s been going on for.

Also I bought him his phone. So am I at least justified in smashing it up or getting rid of it? He needs to pay for what he’s done and yes I believe in karma but I’m also so angry rn I need to do something to release this .
