Search Results: called the wrong name

So, I was out eating with my boyfriend & he was trying to show my something on his phone when suddenly a snapchat message appears from (i'll change the name for anon purposes) Marla. He swipes it away quickly, and I ask, "who was that, whats her name?". He says just some chick, and then he tries changing the subject really fast. We get into the car, and I ask again, "so how do you know eachother, AND WHATS HER NAME?" He insists its just some girl he knows (and that he ONLY has her on snap), and after a while he says her name is Melissa. A lie. I let it go, but the next day I look up the name I saw (Marla) on facebook & instagram. I see he's consistently liking pics, including bikini pics. I ask him again saying, "you obviously know her, and you lied about her name, WHO IS SHE?" he says he has a class with her, so he talks with her through only snap (which is sketch, cus everything dissapears.
Okay, so skip ahead a bit, we're at his house and we took a nap, but I wake up first. I see he had a message from Marla through snap and text, and I know it was wrong, but I was anxious, so I look through his phone. I find out they had been going out a LOT (which he never mentioned), he would call her adorable, offer to buy her food a lot, and that they were planning on taking more classes together next semester. I got mad, because he is the most JEALOUS person I have ever been with, yet he's getting THIS close with another girl.
I confront him about it and get mad that I don't trust him. We almost broke up over it.
After all of this, he still insists on liking her photos and STILL ended up taking another class with her.
I just feel disrespected. How would you all feel?

I would like to share what two of my friends and I would do long ago; it was wrong. I think it was but this guy would never say stop and he was kind of shy.

Let's call this guy John. We were 16 year-olds while he was 19. From Friday afternoon (after school) to Sunday, we would go to the gym. At first it was for workout routines until we met John.

From then on, we would start talking to him. After a week, it progressed to sitting on his lap and complimenting some of his body parts (chest, muscles, etc). At some point, it was some touching and rubbing. We would basically come those days just to bump into him.

It went on for nearly 3 months I think. Then one day on a Saturday, he wasn't there anymore. We heard from someone else that he quitted going to the gym and wasn't coming back. Never to be heard nor seen again till this day. I forgot his last name and his first name is common but I'm sure he must be there on fb.

Armada is 21 years old. And a single mother, And she has a 5 year old son named Able. Amanda was quite angry and fed up with able and one day she called him stupid, slapped him across the face, punched him in the stomach, and chest. Before she could grab able by his hair, her 30 year old boyfriend John punched her in the face, and pushed her to the ground. John yelled at her and scoped up the child. When Amanda left the room the boy started to cry and hugged the man tightly. Was John wrong for doing this?
