Do I have no chance with my ex at all?

So basically I have been trying to move on from my ex especially after recent events but it has been difficult as I still miss him a lot.
He broke up with me at the end of the 1st year of university during exams after only dating for a few months. Although it wasn’t long we moved quite fast and I even met his whole family. I was crushed and I sent him a few texts after the breakup but then went straight into no contact.
Over the summer I was feeling alright as it was much easier to not think about him at home and I was living my best life. I did contact him once to which he did respond but that’s the only contact we had.
Towards the end of summer my ex tagged my best friend from uni in a post and we both found it really weird as he usually never tags anyone and him and my best friend are not friends at all.
When I returned to university I started to really miss him again and start to think about him a lot. I sent him a drunk text to which he didn’t respond but I wasn’t surprised. So I decided to text him again sober asking him if he wanted to catch up and he responded really fast saying yes and he would get back to me when he is free.
I was really excited about this and so a few days later I actually texted him again if he was free to meet because I really needed to talk to him about his friend (who was actually bothering me and causing issues with me but that’s another story).
We met up at his place and at first it was a bit awkward but I made sure to loosen things up by acting chill. It felt oddly nice being with him again and we still had that connection and I knew we both could feel it. We talked for hours and it was really nice.
This is where I get a bit confused, I didn’t bring up anything about getting together again but he asked if I wanted to keep seeing each other again but also he doesn’t have time for a relationship because of the increase in work load and having to apply for placements. I agreed because I didn’t feel I was ready for a relationship either since I study egineeeing.
I asked him if he meant that he wanted to hang out and stuff like that and he said yes. And he also said out of the blue “you know I care about you” and I didn’t hear him proroerly so I asked what he said again and he kept saying never mind, like he didn’t want me to hear which confused me as well.
We made out and stuff (we didn’t have sex) and it was a good night.
This is when things started to turn really sour. I sent him a cheesy text a few days later saying that “I can’t bekieve I almost forgot how cute you were”. He then later when out that night to the on campus club, and my friend was there and saw him. Apprently he asked where I was and wasn’t wearing his glasses (I told him last time that you would look so good if you didn’t wear his glasses), I have never seen him out without them. I was really upset when I found he went out because he literally never goes out (it’s the first time he went out that year) and I’m usually always out and he knows that.
My friend also asked him if he was going to text me and he said yeah but not tonight.
A few days later I unfortunately went out and got really drunk by accident (I’m a real lightweight) and I sent him a few drunk texts and he didn’t respond to any of them.
I felt so horrible that he didn’t responsd and felt like I totally messed up. So I decided I would wait more than a week to message him a casual test saying how he was, and when I sent that he still didn’t respond.
I guess I just feel so crushed because I was doing so well with not contacting him over the summer and things were looking good and then I sent him all those texts and now I feel like I ruined things. I’m trying my best to move on but now it’s even harder since I have seen him recently and it was so nice.
I wish I never texted him after seeing him and I feel like I made myself look so needy. I’m in no contact now and I’m never planning to text him again unless he reaches out to me.
I guess I’m just wondering what do you think is going through this guy’s mind and did I really just mess things up compeltely and is there basically no chance of him texting me now?

@horses634 Yes, you came across as very needy. You initiated drunk texts and texted too many times over a fairly short period of time. If you have a problem with getting drunk, control yourself! Either stop drinking or only have one drink. Nobody knows if he will text you. You’ll just have to wait and see… If he ever suggests a hangout, don’t go to his place. Go out on a proper date and talk.

Good luck.

@patricia12 If I do no contact will I be able to reverse the damage or is it permanent? I just feel like I handled the breakup really well and now all my efforts were for nothing :(. It’s his birthday coming up so I guess not wishing him happy birthday will help

@horses634 If you do not contact, the bad memory of your neediness and drunk texting will fade.

When is his birthday?

@patricia12 Hopedully it will fade, at least now maybe he will definitely notice my absence because I have texted him so much xD. I’m trying to move on because I’m tired of being hurt but I can’t help but hope so much that he will text me.
And his birthday is in a few days, I’m definitely not wishing him happy birthday xD.
