<human>: So I started dating this guy a few months ago. Over time I've learned that he dated a girl long distance for about a year. I never ask about this girl, but I know through mutual friends that they were pretty serious (meeting each other's families, spending holidays together, spending long weekends in each other's cities, etc.). From what I've gathered, they only broke up due to the distance (he broke up with her last year). No falling out or big fights... it just didn't work out. This shows maturity, but at the same time sort of makes me uneasy because I wonder if the feelings ever actually went away. This feeling is solidified by the fact that he still initiates contact with her and she with him. I'm not proud of this, but I checked his phone one time and found this out. He will text her things like, "Remember when this or that happened when you were visiting..." or sends a picture of one of their trips and then throws in an inside joke about it. He wished her a happy birthday and threw in another inside joke... it wasn't just a basic happy birthday text. They send each other songs, saw each other one time in her city after the break up and he texted her that it was great seeing her, and asks about her job, family, etc. I got the sense that she tried to cut it off at one point recently, but he persisted asking why she wasn't responding to him. The contact has slowed down a little bit, he didn't wish her a Merry Christmas, but he did reach out to her brother in law (who he's friends with) and basically asked him to wish her and her family a Merry Christmas. I know it's crazy that I went through his phone, but am I right to feel uneasy about this? Does he still have feelings for his ex? Should I just cut it off now?

Could you distill the essence of the text into 1-3 sentences?
<bot>: New boyfriend still initiates contact with his long-distance ex. I'm not sure if he's just friendly or still has feelings for her.
