For three years, Meaghan was in an on-again, off-again relationship with one of her best guy friends. When she accidentally got pregnant, he supported her through an abortion . Just two weeks later, though, he hooked up with one of their mutual acquaintances. Then he ghosted Meaghan.

As you can imagine, it was pretty agonizing, Meaghan, who asked that we withhold her last name for privacy reasons, told HuffPost.

Three months later, she found out he had gotten back together with his ex the woman he would typically date whenever he and Meaghan were in one of their off again periods.

Though running back to this woman was super in character for him, Meaghan said she was still shocked by the news.

I tried to tell myself that he didnt really love her and that he just needed something comforting to go back to while he navigated a difficult and lonely time in his life, she said. But underneath it all, I knew it didnt matter. I knew we had to be done and that I had some painful emotions to process.

Over time, Meaghan said, shes been able to move forward; shes finally come to a place where she genuinely hopes the two of them are happy together. But as anyone whos been in this situation knows, finding out your ex has moved on with someone else can be devastating.
