Super sad

Sarah
So, my boyfriend had a wife a few months ago but they're into divorce. He said they don't talk. He's very sweet and nice to me but I feel like he is hiding something. I don't know it's weird. Today, right about now he posted a song with lyrics. I saw it and it says how much he misses a girl and fights and how he'll "leave her just for you". We were talking right now and he was replying really fast. He said I love you and I said: do you really?. He hasn't replied. Not as fast. I'm so sad right now. It breaks my heart that he might have someone else or he misses his ex. I'm in tears. I don't want another relationship where they just leave me. 😞
