Just take a clue and give up on her <_<.. You deserve better 😮💨
Rejecting him AND wanting to stay friends is already asking for much, but at least just giving him time to sort himself out, instead of just going and introducing him to someone else after rejecting him would be the bare minimum to expect 😐..
That's really sorta rubbing salt in it at this point, maybe she was trying to be "nice", but the action itself isn't really all that, at this point I wouldn't even mind it going the BL route and him getting together with his master, once the cat is out of the bag 🫡
