She probably made a copy of your apartment key,just tell your landlord she's crazy and may have a key he will change the locks. Might be best if you don't tell him about the green beans though.

Pretend to make a call to pest control if she is living in the walls she would probably leave I would also change locks and setup cameras in your room before you sleep

Am I the only person who interpreted this post to mean OP doesn't use his microwave oven very often, and stumbled upon a gross, mouldy bowl of beans?

Bad April fools joke- or you need to do some serious spring cleaning.

Why does everyone think there's a weird green bean-leaving stalker in the house? It makes more sense that the microwave just hasn't been used since she was there.

who doesn't like green beans? seriously, I don't know anyone who hates them

That's what she wants you to think

So either 1. You haven't used the microwave since she moved out so that bowl has been sitting there for 3 months. 2. She's crazy and flounder a way in to leave that bowl of green beans as a warning of some kind. 3. It's a joke someone your close with played on you to freak you out. Either way talk to your ex and your friends about it in a calm and adult manner. Because that's the only way you can get your friends to fess up and or that's the only way you can get your ex off your back. If it was her she wants to freak you out so don't let that show.

Wtf do you mean "my" microwave? Thats not your microwave. Thats not even your house anymore. You're moving far far away.

Or did she......dundundun.
