What should I get my boyfriend for Valentine's Day? We've been together for 4 years it'll be 5 years in march I'm 18 and he's 19

This is not a school related question, but i will give you an answer

Well, first of all congratulations. 4 years is a long time.

You don't have to get him something expensive, I'm sure he will appreciate a homemade gift (perhaps a collage of photos of the two of you). Another suggestion is a short poem, a video game (if he likes video games that is). Last thing that I can think of is on pieces of paper, write reasons why you love him and then putting those pieces of paper in a jar. Cheesy I know, but I think it's cute haha.
