Ex is getting married!!!

Hi Guys! I am 26F.. I was in a relationship with a guy I met via Tinder in 2019.. we dated for almost 5 years out of which the last 2 years were long distance. We are both from Delhi but he moved to Hyderabad for work. So… 2.5 years into the relationship he told me he didn’t see a future and we weren’t compatible. I was vv much in love and vv attached to him and thought that when the time comes things will get better(delulu, i know).. last year in march he decided to end things saying ki his family wants him to get married and he wants to end things amicably and he thinks that I am immature and not ambitious because of which he thinks we do not have a future.. we stayed in touch initially and then a month later he told me he is going on dates.. he told me he met someone via his father and that he sees future with her.. initially i didn’t take it seriously.. but then later I realised he had been meeting her for a while and on strict warning from my friends I went on a NO CONTACT with him and stopped talking to him. But we were still following each other on instagram.. He got rokafied to that girl in July and is now getting married to her. 2 weeks ago, I came across an instagram page for their wedding which had a post about their love story, which mentions that they met via Bumble and after connecting the dots and a lot of stalking later I figured out that he was on a dating app and had been cheating on me for almost 3-4 months (probably more than that, this was the one girl I could see must have been more). Delulu as I was I confronted him and asked him to tell me the truth he still kept lying that the social media post was just to show others that we have known each other longer and social media is a lie. I have always been loyal to you.. etc. i just made my peace with the fact that this guy is nothing but a liar.

Yesterday he had his sagan and they both danced to Dilli waali Girlfriend. Idk why I just felt vv bad when I saw that it literally felt like a dig at me.

If anybody can help me with any suggestions why I am unable to move on or tips on what I should do.. please let me know. Don’t be harsh pls. Thanks🥺
