I admit I have oneitis after my fwb dumped me and got with another guy on tinder.

This girl is batshit crazy. She is borderline. She even told me that she goes clubbin with this guy met on tinder.

I now the RP, ignore and move on. But as everyone gone through oneitis knows this is really hard. Now my question is, should I send this guy a message and inform him about the craziness of this girl?

If he plays as I tell him he will fuck her and never get hurt. Other than that, she will mentally kill him.
