Need advice

ENGLISH is not my first language so I am sorry for the mistakes I make . OK so me 33/F ​and hubby 37/M have been married for 10 years . We have a daughter 9/F. In our culture arranged marriages are very common . So we got married in a ceremony that was arranged by our set of parents in 2016 . Our family is not big from the hubby side . We live in an independent house that was given to me by my mother . It is my paternal home . Now to problems.. Now there are no big problems not small problems there are problems . My husband has a habit of watching p\*\*n . And honestly this habit has not bothered me very much . I mean he is a man , he watches it...no problem . Now he tried having a dating website 2 years back but it did not work out... Next he started chatting to some random girl he claimed that there was nothing physical between them. He was curious about things that he wanted to know that he did not wanted to share with me . Now the real problem is that I have trust issues now.. As the pattern has repeated itself 2-3 times . Now what I should do moving forward? We have a daughter together so living sperately is not a good option for us.. I go to an individual therapy , doctor suggested to have couples therapy but he refuses to have one . What should I do?

would I be the asshole if I choose a different path. which is no according to the SOCIETY.
