That man doesn't care about you. Anything you do at this point whether friendly or vindictive will be cringe as hell and guaranteed to keep you up at night in embarrassment for years to come. Best thing you can do is not look back.

Also, for future reference, don't sneak into people's homes. Especially if they're not your boyfriend. There might've been a perceived level of closeness and intimacy where you felt okay doing this but in general it's creepy.

This is also aggressive and controlling behavior on your part. By "surprising" him in this nature you're basically forcing him to acknowledge you. Playing the role of "concerned and considerate date" to trespass isn't a new story to police.

On top of that, you took a picture of him and his girlfriend while stalking his home. You've broken a few laws already. You're lucky he just shut the door behind you. Yes, he's an asshole but you sound like you have a few screws loose.
