My wife betrayed me, how should I face it and ask for help!

My wife and I met and got married 1 year and a half ago. We have been married for more than four years now. Although it is not vigorous, it is also very smooth and smooth. Although married life is dull, it is also satisfactory. Now we have a little girl who is almost 3 years old. She is an idealized person with a small circle of friends. I have a bad temper, poor health and a bad job. I often lose my temper. I used to be very kind to my family, but recently 1 year, I have changed a lot, and I don't respect my parents as much as before. And always discuss emotional problems with me, often say some rude words when I lose my temper, but I fully understand her, although not very positive, but also take the initiative to comfort her. She is 30 years old and I bought her a diamond ring. The purpose is to let her know that I still care about her. I am currently starting a business, and the company has encountered many difficulties. Sometimes there is no time to take care of too much at home, and people may be lazy at ordinary times. She is a little dissatisfied with me, and I can understand! Many changes have taken place in my family this year. When I was dealing with the changes in other places, I was bored and didn't plan to check her phone and SMS records online. I found that she and a friend of mine often send messages, and both of them are sent when I am not at home at night. To tell the truth, I felt it before, but I was stupid and didn't think about it anywhere else. It seems that there must be a problem, but I'm not sure to what extent. After I came back, I began to pay attention to their communication, which seemed to be limited to texting. Because there are too many things at home and in the company, I haven't delved into them, and I have been thinking on the bright side, because that boy is a relatively petty and dark person who loves to stick, and they sometimes have business dealings, and I don't want to divorce! Therefore, she seems to know how to beat about the bush, but they got in touch later! I'm a little desperate and ready to collect their direct evidence, which means I'm ready for a divorce! The content is probably that he invited her to dinner, and she readily agreed. The two languages are very tacit! On the day of the treat, I don't know whether I took the children out to play with her or what, they didn't come! Then the boy went on a business trip, and my wife sent him a text message to make an appointment for a new time. The boy said that he would talk about it when he came back. The wife said he was in no hurry, and the boy said he was in a hurry. My wife's short message comforted me. The content is probably: "She doesn't want to, just want to find someone to have a quiet meal. If that's what you mean, let's change people! " I feel much better after reading this short message, and I also judge that they have not gone far. I'm going to find a chance to clean up that boy and then make it clear to my wife that I hate their contact. So one day I told her what I thought after drinking, and she seemed shocked. We basically made up, although we were still uncomfortable, but we didn't think too much. Now I'm ready to start cleaning up that boy, and I told her through my friend that I'm going to take action. She seems to be worried and doesn't know what she is worried about, but she is much better to me and always says she is worried about me or something. The reason why I want to tell her is that I'd better sound her out. I wanted to embarrass the boy in public and beat him up again, but then I changed my plan and prepared to end his political life. But obviously, I found that the boy was more alert to me, including my best friend! At this time, my wife went back to her hometown on vacation. There is a short message between them. After she came back, I looked through my mobile phone again, which really made me ambivalent. Although the content of the text message is to interrupt the contact between two people, the text message clearly tells the boy that she loves him! ! ! Tell him I want to act! I want to leave now, because no one can stand his wife claiming to love another person! Whether they have betrayed me physically or not, this kind of spiritual betrayal is really unbearable.
