Should I give up?

Okay, this is gonna be one heck of a story, so, be ready for a long read.

Early to mid March, my boyfriend said he was feeling confused on what he wants in life, and said he needed space. I agreed, and told him I woukd help in any way I could. Well, some time passed, and he said he DID NOT want a break. I agreed. Well, he continues to tell me hes confused, and give each other more space.

On April 2nd, we break up because he feels like he needs to be alone to make this decision and says he feels like hes screwing me over by the lack of hugs and kisses and pushing our dates back (long story, he never wanted to push our dates back). I said I understood all of it. He then says he feels like hes making a mistake and if we ended up getting back together, hed ask me to marry him.

Well, the following Wednesday (4/5) we hung out and it sounded like we were gonna get back together, and we had sex.

The next day, Thursday night (4/6), he texts me and says he misses me and he doesnt want me to move on, but he also does want me to find someone better obviously showing his confusion.

The next day (4/7), I try to ask him about it and he tries to tell me that he just was really depressed that night. I didnt believe it, but I went with it.

Well, we hung out again the 10th, a Monday. I asked him if he liked a girl in one of his classes, and he said he didn't, not like a relationship. I asked if he was still confused and he said not really, but still a bit about us.

Well, the next day (4/11) he says he thinks he knows what he wants. He leaves me, but changes my nickname on facebook from Princess to Pure Life.

We don't talk again until school starts back up again (4/19) and I try to give him his stuff. He only takes one jacket. I ask him if he's absolutely sure this is what he wants. He hesitates, and says "yyyyeeeeeeeaaaaahhhh, I'm soooorrrrrryyyyyyyy" really slowly and he sounded very uncertain. He was walking with the girl I asked about a few days ago, only a lot more. I played no mind, but something told me they were together.

The very next day (4/20), I learned that they were dating. After only 2 and a half weeks. I lose my mind. I decided to confront him about it, and he avoids it, so that was basically my answer. I ask him if he still loved me, and he says he moved on and tried to tell me to do the same, and that he was dating her because she understands him (not nearly the way I did) and they were super similar (he hates himself, but is dating a "female version" of himself). I personally doubt he could have moved on so fast after 1 year, 9 months, and 5 days, and talking about marriage and how he wanted to propose. Well, I make him take his stuff back by the end of the week, and we dont really talk much after that.

Well, suddenly, around 1 AM Monday morning he texts me and says that despite everything that's happened, he hopes I'm doing okay. I tell him the same thing. He then tells me about his day at work (I didn't ask), and falls asleep shortly after. We've been talking almost every day sense then, but, only when his new girlfriend isnt around, like 4th block. He says if we wanna talk, it should be over text or during the classes we have together because I make his new girl anxious.

A few days later, he texts me while hes self pleasing (not his girlfriend- he texts me. He almost slips and asks for pictures, but doesn't and says he needs to stop talking to me while doing that because "bad memory" and almost asking me for pictures).

I'm not sure if hes happier without me or if his ADHD has been acting up, but he seems a lot happier.

However, when we talk during class, it feels like hes trying to flirt, and I'm falling in love with him all over again.

My cousin says he's completely moved on and that its pointless and that I should just give up and that he told her that he really likes his new girlfriend, even though hes never told my cousin this kind of stuff before. I dont think he couldve moved on so fast unless he fell out of love with me and didnt tell me. Some of my friends say to keep trying and keep going. They say he still loves me and couldn't have moved on so fast.

I find out that his new girl can be mentally abusive after some time, but, being the ex, I can't tell him that.

My heart, mind, gut, and soul are all telling me to keep trying to win him back. But my cousin makes me feel like I just need to stop and that these feelings are irrelevent. My friends (including a girl who overheard the conversation) think he's gonna come back and that hes still got some stuff to figure out, and that this new relationship he's in will blow up in his face.

I don't know if I should keep going, or just give up. I really need advice because he notices small things still. Like when I cry in the morning he can tell in the afternoon that I cried that morning. His new girl doesn't want him talking to me, but he still does. I just dont know what to do. I keep having dreams that he's gonna come back, and stuff. I feel like he'll come back, but I don't know if thats false hope. I want honest answers only. Hes the love of my life and I know his depression is coming back. I don't know what to do. I want to keep trying to get him back. And I'll do anything I can do get him to come back. What do I do, ladies? (He broke no contact btw.)
