My boyfriend said He's falling in love with me!

He's never said anything like this before, we've barely been together a month but everything seems perfect. I know we're in the honeymoon phase, but he's the best guy I've ever dated.

We were texting and I mentioned how much I already miss him and that if he wasn't busy, I'd make him spend all day with me and after sort of agreeing, he just texted me this. I didn't even know what to say and I still don't.

I really do care about him and want him to have everything that makes him happy and be there for him when he needs support, but I don't know if I can just text him back, "I love you too" or what. I don't think it's something we should text each other when it's the first time. What do you ladies think?
