Moving 1.5 blocks away from Ex

Hello. I (m25) just bought a house and closed on it a couple days ago. I have an ex, we can call her ‘Kay’ (f20) that moved into her house her dad bought her in Aug 2024. The thing is the house I just bought is 1.5 blocks away from her house. I bought the house tens of thousands of dollars under the market value so it was a good deal I couldnt pass up on. I don’t want to seem like a stalker if she sees me driving around or anything. Should I tell her I live near her? We didn’t break up in bad terms which is good. We respected each other. Her and I broke up November 2024.
