He's trying to get back with me and tells me he loves me and wants to marry me. He made it seem like he didn't have time to date or hook up because he's so busy with school yet today it came out that he has. I'm so upset and don't know what to think. I know I can't technically be mad at him but also feel misled at the same time. Like why did he feel the need to not say it then say it now?
