Ex bought me valentines gifts?

So my ex's mum has just dropped off chocolates and a big bunch of Rose's from my ex. Also a teddy bear and chocolate heart lolly for our daughter. We split 4months ago and I really dont think theres any chance for us again and he knows that, so why would he buy me gifts? He still loves me and I know that but we aren't together. It was a really lovely surprise and I've messaged him to thank him but its brought up those feelings again and I'm really not sure why he would do that. Our daughter is only 3 so I could understand if he just wanted to set a good example of a man for her but she has no concept of valentines at all.
