tolerate it? No I do not "tolerate" anything that my dh does. If the question was meant to be am I bothered that my dh watches porn, then no I am not.
I have know "real violence" @OP (so I hope it's ok for me to post 🙄), the kind that puts u in the icu in an induced coma, but that is physical violence. What u have done is physical violence, however whilst a glass of water to the face may not hurt him physically, it can hurt emotionally, which is just as damaging. Also, if you are married (I missed whether u were or not), then u have also broken the law by throwing him out as he has every legal right to be in the marital home. (If you are not married then he may still have the legal right to entry if you rent and are joint tenants or he is a joint owner/pays towards the mortgage.)
Now as for the porn, you are totally at fault here. You have said that you have not had a talk where you explained that porn is a deal breaker for you (obvious by his not hiding it and giving you free reign over the phone), therefore he absolutely cannot be held responsible for not reading your mind. If he was aware that it was a problem for you then it would be him in the wrong (although, still not wrong enough for you to attack him).
It is not ok to hit anybody but I am very glad for his sake that u 'held back' as had you hone further he would have had every right (moral and legal) to defend himself and then probably would have found himself branded an abusively violent porn watching bastard.
With regard to your dd (12 I believe) why would she be having unsupervised use of a phone that can obviously connect to the internet? Have you asked your oh about this? Regardless, if that was the issue here you would have said so in the op as that is quite a vital piece of info to leave out (and a massive drip feed, which most experienced mnetters will tell u is 1 of the biggest bugbears going)
If there is any coming back from what has happened today, (I couldn't honestly blame him if he told u where to go, could u?), then I think anger management for you and communication therapy for the both of you is needed as this is a conversation that should of been had when you first got together.
