Of course your husband should not blame you and he must take responsibility for how he has hurt you with his online behaviour, but the two of you must take responsibility for improving the marriage.Though it may be painful, the fact that you have started talking about issues is a good sign.
For example you can prioritise a daily talking time with your husband when you share how each of you are doing.
To continue with this process you may wish to seek marriage counselling ( relationshipsireland.com, accord.ie).
There is a good chance of success for the two of you, if your husband accepts responsibility for what he has done and if the two of you are willing to work hard on improving your marriage.
A second issue for a marriage is that one partner turns to the internet for flirting and sexual excitement rather than to their partner.
When this happens frequently, it can lead to a reduction in their sex-life together, a growing sense of disconnection and an erosion of the marital bond.
Real intimacy is created in everyday communication, in the nitty-gritty of sharing a life together and in the hard work of resolving conflicts and accepting the other person as different to you.
