My husband was chatting with friends about whoring on QQ, and I found out. ......

Since we don't want to be apart, there are only two ways:

One, regardless, out of sight, out of mind.

Second, if you are a self-respecting woman, put yourself in his shoes in the face of his refusal to admit death. You also approach other men (without doing anything) and let him know. Similarly, you also find a bunch of excuses and see what he does. If he still loves you, the family who loves you will immediately realize how you feel now and sincerely correct it. If he doesn't repent, then you really need to re-examine whether your marriage is necessary.

No monitoring can always work, and the distrust between husband and wife will always enter a vicious circle.

Personal opinion, for reference only.
