Y... Me di cuenta

It's been coming for about two weeks now, at first I thought it was normal for colleagues from the faculty to hang out, but little by little I started connecting the dots. I found out that they were forming study groups and my wife is the only one in the group (well, according to her, since the others are bitches), so that's why they came home. Then on a birthday she organized alone at home with all her friends and some girlfriends, and one of them slipped up saying go ahead, you know the house well to another guy, at which point I let it slide and later found out he's the one who comes here most often and I work from 7 pm onwards. Later I noticed she was very expressive when greeting and even when greeting our neighbor, a guy who's barely 18 years old, so I made a comment about it and she got really upset, but going back to the previous case, I saw a huge change in her behavior, she no longer cared about speaking freely with anyone and wasn't careful about mentioning fuck anymore. She changed a lot and started praising one of her colleagues who just happens to be the one who comes here most often and according to her is because he's the most responsible when it comes to organizing groups. The fact is that someone like me, a retired pirate, recognizes certain signs, this guy just got separated and always had contact with her, because according to what she told me, she understood him, several times bringing him from the faculty, since they would leave late and always bring a skinny guy I know who's half gay. About a month ago or so, he sent me a message while we were eating dinner and told me it was that friend of hers who used to bring her before, complaining that she wasn't making more groups with him or wanting him to bring her home, at first I thought it was funny but later realized she hadn't mentioned anything about not bringing this skinny guy anymore and asked her who came over and named him. A few days ago when he entered the house he was surprised and when I went to give him a kiss I smelled something weird, something familiar... cock smell. I remained silent and didn't say anything, eventually he left. To the bathroom and I take like 15 minutes and when she comes to the table I ask her what happened and only answers that she feels bad. We eat and go to sleep, that night I don't touch her and neither does she ask me to. At midnight I get up to the bathroom and notice that the underwear I had on in the morning before leaving for work was in the shower and still wet, a sign that she changed it before sitting down with me at the table. I've known her for several years and know when something changes suddenly in her and why. We always make love but lately she uses words like break my ass, put it in my butt, give me all the cum. I can't say it doesn't get me hot, but she still lacks doing it right. A few days ago I called because already an hour had passed since she usually arrives from school and after several calls and messages she answers me and says agitated: What's up? The professor gave a new exercise and we couldn't leave until we finished it! If you don't believe me, I'll pass... we just left, I'm going down the stairs!! I hung up, at that moment I realized I was getting screwed and not sure if it's the first time, but I discovered her. Last night she said: Tomorrow I have to be early at work and then I'm off to Avellaneda in a taxi. This morning I wake her up, warn her she'll be late, she gets up, takes a bath and looks very worried about what she's going to wear and is late... Suddenly I look out the window and don't see her, we live in an apartment building and the bus stop is right across from it, and couldn't have taken less than a minute to get down, cross the avenue and take the bus. Today I didn't work, yesterday she didn't know I wasn't working today. And before she left she said that in the afternoon she was going to her friend's hair salon, another nutcase like her. Sorry for this post, but I don't know who else to talk to about it and it is It's hard for pirates like me to have my ship attacked like this, so please tell me what you think. I'm about to fulfill some of your fantasies and see how you react.
