Valentine's Day gift ideas for my boyfriend?

We've been together a year and a half and my parents are in the middle of a divorce so he's been helping me out a lot. Basically he's amazing and I want to do something sweet for him but idk what to do. I have a very small budget even with my job, I have to pay for driving lessons or it'd be bigger. I was hoping for some suggestions of just sweet things to do for him. Ideas?
