What does my boyfriend mean by "You deserve better" has he lost interest

We've been together a month he's already said I love you to me a few times after about 2-3weeks and I never said it back just said I'm falling for him or really like him. Now I really have fallen for him. He hasn't said it in a while. "I know this sounds crazy scares me a little by saying it but I'm in love with you I know you've said it already just hope I don't scare you by saying this now like maybe you've changed your mind just wanted to tell you and I really mean it" I sent that to him on whatsapp then his last seen came up about a minute after and he didn't reply and hasn't been online again so nervous even more now. We've been speaking about for ages how we have such a great connection. When he told me he was in love with me he said "You can shout at me for being crazy but I'm really falling for you baby. Like really hard babe!!!xx" then said "I really think I'm falling in love with you (my name)" and has said it a few times and another time when he was drunk about 2 weeks ago. We spoke a little earlier about the concert and then today he sent this "I'm going to be honest pet. This is scaring me how fast things are going with us . I really had no intention of getting into a relationship until I met you :( . I dunno what it is. I'm afraid of hurting you and myself :( I'm just confused" I sent this "you know what I said yesterday I think I may have got confused with the whole love thing my own feelings. I do like you a lot I didn't mean to scare you but I honestly said it in the heat of the moment. Do you still like me . I really think we should meet up and talk it through it'd be easier" Then i sent this " "I do care about you thought you were a good guy. But I don't want to be messed around by someone who doesn't know what they want". . He replied and said this "Like I honestly don't know whats going on in my head. I really don't. I hurt when you said "I thought you were a good guy" I am. I've always treated you right. I just don't know what I want in life right now. I hate my job and most of my life to be honest. I'm not the right guy for you :( you deserve way better"
