My ex-boyfriend, who I dated a year ago, contacted me. What do you think he’s feeling?

He’s the ex who broke up with me a year ago. He sent me a LINE message saying something like, “Long time no see! How have you been? A close friend of mine just opened an esthetics salon, so please check it out if you’re interested!” He also tweeted: “My best friend, who’s incredibly beautiful and has an angelic personality, just opened an esthetics salon, so please go check it out if you’re interested!” That close friend is a woman. He doesn’t know that I know his Twitter account. He probably isn’t interested in me anymore and just messaged me without giving it much thought because he wanted to help his friend, right? I still have feelings for him, so this has really shaken me up. It’s painful. I want to forget him as soon as possible.
