I feel so guilty!!

I was at publix earlier today and I saw a family- husband, wife, two 4-6 y/o boys. The mom was looking rough. She had sweats on, hair in a bun, and no makeup. She also looked exhausted. Well the husband would not stop looking at me. Like hard core staring and wasn't trying to hide it. I saw them in like 4 isles and every time he stopped everything to blatantly stare. And He freaking smiled & winked at me in the bread isle and I just looked at her and she looked so sad and defeated and I know I did nothing wrong, like I didn't say anything to him or give him attention but I can't help but feel guilty. The expression on her face broke my heart and I just wanted to hug her. Idk I had to get that off my chest. He seemed like such an asshole.
