Am I just over reacting?

[So]

Hi! So I am a young adult I should 22 years of age and he is 24 years of age. I have a boyfriend of almost 2 years.
We been having this on going problem, that I had thought had went away but just started back up again. There is this girl who I shall call Carley, She known him since he was 17. But its all started because he liked her. He has told me that he had chased her for along time before his last relationship of 2 years with the canadian. And that when he left his ex of 2 years he went right back to chasing her. He went on to tell me that they did have sex when she got drunk at his house. Then she started to date someone else almost right after and she stopped talking to him because he told her that he did like her boyfriend. And then I came along.
When he told me all this I really didnt like it but she wasnt talking to him so I felt there was nothing to worry about.
But then! Carley broke up with her boyfriend and went right back to kevin. At first I tried to ignore it. But one day he left his phone on with his text open and i saw him complaining to her about me!
I was upset and was talking about leaving me and that I was to jealous. There was so much and the way he talk to her sexually. He said it was a joke all the sexual stuff. but after a fight he had agreed not to talk to her.
He took her off all social media right in front of me.
Then today happen. I had this feeling that was right and yes I open his phone and looked at his messages. and there she was.
the first thing i see in the message was.

Her: your old
him: But I still fuck like im 17

she goes on calling him old and then i read

him; i just wanna see those tits

then he goes on about a coworker
and then goes on about how i super jealous and wont let him do anything
she calls me crazy.
i dont remember the rest something about them being best friends

i dont know what i should do... how should i act about this... am i just in a pointless relationsships
and why do i feel so cheated on?

Young adult or not - you are not stupid. You had this issue before now it is reoccurring. First it is odd unless you specifically why was he telling you about fuc*ing her. Isn't that out of place? "He went on to tell"/"She got drunk". He included those details too? Talking about sex.. That seems odd. Sometimes people "overreach" with honesty thinking if I exaggerate or be extreme here. Later you will overlook it thinking what kind of an idiot would they be to do it when they told me all about it. HE made it clear he liked and chased this girl for 7 years (since he was 7). Later you caught him in an emotional affair having cyber with her? (Was that is?) Talking with out girl about ex's is not bad but all of this together is odd. Like he wanted you to be jealous/overlook (misdirect)

Now today or within last few days. He is talking to this slut. She knows he is with you, she is intentionally doing it. He is himself look great to her putting you down and she is talking trash about you? She does nothing to remind him when he wants to see her **** or fu** her he has a woman. Go see her now. Let her know what a ***, ****, *****!!! ***** ******!! she is . While possibly not for long that was our man. Don't let people do that.

Have you done everything since the last problem to demonstrate forgiveness, within your comfort show him you forgave him and worked harder to fix the relationship. This is not your fault. But guys are emotional too. Any chance he might have felt pushed away?

If not he is a douche, sorry. A cheater, liar who is intentionally doing things without your knowledge, pretending to fix things while dong the oppisite, being rude/callous and having a physical/emotional affair. He is doing this with a slut who knows about you, talking dirty with your man and sh*t talking you.

YOU FEEL CHEATED ON because you are being cheated on. Grow some "Balls" / T!ts So. Talk to this girl and kick him out
