Memories kill me

So I went to the same college as my boyfriend and we shared so many memories there together when we first met etc. he’s not coming back to school, we are still together but I can’t help walking around feeling empty at school. I feel like there’s a void because he’s not there with me ? If that makes sense. I just picture every scenario in my head whenever I walk passed a certain spot and it makes me more sad.🤦🏼‍♀️I sound crazy lol
