I need clarity on my feelings if you can answer me questions below?

I need some advice guys so So I don’t think about my old school crush any more who I liked since I was 12 up until 25 , as I’m now interested in other men as crushes but one thing I’m confused about is when I’m outside and near my old crushes house or his area I’m scared to come across him and I don’t want to see him I feel scared and I want to avoid him and his road , I wanted to know why would this be the case if I’m now starting to have crushes on other men like different men at a time which last not very long these crushes as I jump from one crush to another , but I also have this fear when I’m outside that what if I bump into my old crush and I feel anxious why is this the case?
