Tassy I think you really need to write all the good things about him down and then all the bad. How many days you feel angry and how many days you feel terrible and make a decision whether you should stay with him or move forward without him.
You have to do what you feel is right for you. I personally dont see porn as cheating but i am aware of all the problems it can and does create in a relationship. It can even lead to sex addiction and prostitutes etc in extreme cases especially in middle aged men who use it as way to deal with stress.
I understand why it bothers you-everyone has a different opinion on it but i think the kind of porn that is so easily accessible today compared to 20 or 30years ago makes normal sex look abnormal and lots of men get confused between fantasy and reality. That is when it becomes a problem.
If he gave up so easily on counselling the first time round, he may not be willing to fix the problems. You both eed to go wholeheartedly and both really want your relationship to get better for it to work.
If you feel you are giving a lot more than he is-it may be a good idea to throw in the towel and just look after you. Be selfish for once and focus on making you happy. It is your choice of course.
I wish you luck abd happieness xx
