Old ocd resurfaced or i m bad

Hi guys. I m 33 year old male. I was diagnosed with pocd in 2014. Did ERP and anti depressants for 3 years. I became alright for 5 years.
Now again things are turning worse. My wife became very un loving towards me. I requested her to love me. But she was busy. She used to hurt me emotionally. I got attracted towards a colleague and we got involved physically..
Now i feel that i want to have sex with every beautiful lady. Same pocd kind thoughts coming again that i want to have sex with children and all females. I look at females sexually. I feel disgust over my attitude. I aant to be a good man. I almost feel that i have become a monster. I feel depressed. I want to become same old good man who had nothing to do with other females than my wife.
Thanks
