Sexless marriage

After I got married at the age of 27, I never watched porn until the end of my wife's pregnancy. This means that I managed not to watch porn for about 15 months, but I benefited a lot from my wife. Sometimes I would come home from work and have sex during lunch break. This situation seemed strange to my wife and she had no appetite, but even if she was coy, she would usually accept me. Of course, it would be much more difficult if she wasn't a housewife.

At the end of my wife's pregnancy, my wife caught me watching porn and became alienated from me, very angry with me. She didn't have any sexual appetite anyway, I was always initiating it. She doesn't need sex anyway, and when she cooled off from me like this, things got worse. Now a vicious circle had formed. Porn was catching up with me because she was running away from me. That's why she is becoming more frigid. Even though I begged and apologized many times, I could not break this vicious cycle. It's just that his respect for me has diminished.

Now the baby is already over 2 years old : It feels so humiliating to be satisfied with porn instead of my wife. So I get angry and rude towards him. I can't manage to treat him well. It's like this: After I've been nice to her, it really bothers me when she rejects me at night. That's how I become an angry man. Since I'm a grumpy guy who watches porn, she gets more frigid. This vicious cycle is making our marriage worse every day.

What shall I do about this?
