A gay man in Quezon City, Philippines, slit his wrist and tried to jump from the window of a 16th-floor apartment after pouring acid on his boyfriend.

Wearing only his underpants, English teacher Joseph Fedelin, 44, hugged a pillow as he contemplated leaping from the high rise yesterday morning, distraught after breaking up with 32 year old call center agent Jefferson Quitaleg.

Quitaleg said they had just had sex when Fedelin poured the muriatic acid on him.

The couple of five years had been fighting on Sunday night after Fedelin found out Quitaleg had been cheating on him with another man, the Philippine Star reported.

It took rescuers around two hours to bring Fedelin to safety, after which he said: 'You men, be faithful to your gay lovers.'

Both men were treated for their injuries, with Fedelin later jailed and facing charges for serious physical injuries, alarm and scandal.

Quitalig is currently being treated for chemical burns on his face at Capitol Medical Center.
