So my ex broke up with me 2 weeks ago after about 1.5 years together on-off long distance. It was completely out of nowhere. The day before he did he said how much he loved me and couldn't wait to see me and how great I was. The next day he just said something is different. I was shocked and heartbroken. I tried to fight for him back and our relationship in the moment but he had already made up his mind on his own. However, we kinda ended on good terms after talking it through. I started NC 2 days after we broke up but only replying to his messages when I had too. Well a couple days ago he posted a photo of him and a girl very close together. All of his friends liked it. I don't know what it means but I think he is dating this girl. This really hurts that it hasn't even been a full 2 weeks and he's with someone else. It doesn't make sense to post something so new on social media does it?

I'm still in love, heartbroken, and so many other mixed emotions at once. I feel like he might've posted it to make me jealous but is actually seeing her. I know they met very recently. I think it is childish to try to make me jealous if that's what he is doing. What do you think?
