Is this a red flag? I’m scared to catch feelings again

I met this guy about a month go and he is going wayyy too fast I feel like that’s a bad thing isn’t it?? I heard it was.

I heard that’s a form of manipulation but I’m not sure. We’re teens by the way so I know he’s not “in love” with me lol

He sends me paragraphs every day about how much he loves me and cares about me and idk something seems off because he doesn’t really KNOW me yet. I mean yeah we talk every day but he doesn’t know me.

Like read this thing he send me earlier when he told me he loved me. I asked him why he thought he did and this is what he told me.

“I’m in love with you because nobody has ever taken care of me and shown me love like you do and you make me so willing to do anything it would take for your love.”

......

Then he said this morning “Good morning baby girl you mean so much to me and you take the absolute best care of me. You make me so happy and make me feel so warm inside. Every day I get to wake up and say that you’re my girl and I belong to you and nothing else makes me happier. I can’t wait to have you in my arms lovebug”

I really like him but I have such horrible trust issues and I always feel like people lie to me when they show a lot of interest due to my last toxic relationship that lasted about four years.

Idk I’m just really confused. I like him a lot it’s just I’m very scared to get hurt. Seems too good to be true.

He’s not really like other teenage boys which makes me want to believe him. He’s different in a way almost too mature for his age which freaks me out because I’m still childish.

I just don’t understand why someone could love me. Like why ME? I’m literally nothing special.

We’re not dating yet btw
