Is it time to walk away?

The main points here are that you do not trust this guy so much as an inch and that he is totally unwilling to do anything to win your trust.  Relationships can survive a lot of things, but neither complete distrust (Your feelings towards him) nor utter disrespect (If he cared one whit about your feelings, he would not keep flirting with random girls).  I do not see a lot of hope for your relationship from either side, I'm afraid.  It may indeed be time for you to walk.

If you do not feel you can forgive him or he can avoid further betrayal(s), then it's likely past time for you to depart.

Ashley.. ignore all the negative comments here. You ARE better than this! In the end, what matters is that YOU realize your OWN WORTH! And you know what.. sometimes relationships don't work out. And it's not either one's fault. But the bottom line is.. YOU should feel happy and LOVED. And if you don't; GET OUT. 

ALWAYS remember that you ARE a gorgeous feminine woman.. you ARE worthy! You dont need to prove your worth.. or feel ****. It may not be his fault that you do. But if you're in a relationship with substance and a future.. you WON'T!

Be as GREAT as you are! You ARE worthy! You are BETTER than what you make yourself to be. I know none of us wants to hear this; but you HAVE to love YOURSELF FIRST!

Thats the key step to being happy (and irresistable to your guy). You got this, babe! Dont let ANYONE put you down! It's HARD to be a woman.. and it's REALLY HARD to keep believing in yourself without validation. But you got this! If he loves you.. he WILL make you feel loved. If not.. you deserve BETTER!

What? Your writing is confusing.

I've read this a few times and your poor grammar makes it confusing.

You say "a lot of people reaching out to him" - What do you mean by this? Reaching out for help? Calling and wanting to hang out? Is he a boss over a company & employees are reaching out often for help?

" I do not know these names so, I worry." - These names??? So is there like a huge list of names that you want to know or do you mean "I do not know their names or who they are." Again your grammar is hard to understand.

"I asked if he could be honest with me and call out his friends' names guys/girls so I wouldn't get worried " - Call out his friend's name? You mean shout out because that is what it means to call out. Or do you mean you asked your boyfriend to introduce you to his friend and he said no?

"Also, he lied to me about a girl for months and they would continue to txt and snapchat" - So is he not allowed to have a friend who is a girl? Or are you trying to say he had a girlfriend on the side?

"We had a huge fight and I felt like **** for months. I have gotten better" - You got better from what? Were you sick, depressed?????

"he decided to follow her on Instagram, knowing it was bad news." - Just why is it so bad that he follows her on Instagram? I've been married for 25yrs and have male friends that I follow on Facebook and Instagram.

Again with all your poor grammar, it is very hard to understand what you are trying to say. But, it does seem like you are trying to control him and tell him who he is and who he isn't allowed to speak to. It sounds like you have very poor self-esteem too. Therapy can help you. It seems to me you are not old enough to be dating again based on your grammar. Finish school and finish growing up a bit then later when you feel secure in who you are you can try dating again.

Update- "Thank you. But, this "friend" was from tinder and they have hooked up. She was constantly hitting him up to "hang". Thoughts? " - So why didn't you mention that before? Again this just shows how poor your grammar skills are which makes you sound more like a child, not an adult. An adult would have said this right up front. If he is still seeing someone on the side then he is cheating on you.

He's allowed friends & can follow anyone he wants to follow it doesn't mean he wants to have a relationship with them, he is in a relationship with YOU, he loves YOU, he spends his time with YOU trust him a little bit more I know it's hard if you are a jealous person as I am jealous also but you will only end up losing him if you continue to act like this as he has done nothing wrong.

Yes, do the guy a favor, and walk. Then grow the F up. You sound like an immature child with no clue how to be in a relationship.

Yes. And after you walk, find a way to grow up and understand that most people meet new people all the time. They cant possibly "call out" every name of every acquaintance. Constantly assuming anything, much less "the worst," isn't going to be good for you or any relationship you have in future. Your insecurities are yours, not his or anyone else's to fix.
