I said i love you and now....?

I’ve been dating him for almost five months and this weekend i told him i love him. he told me he loves me a few weeks ago, it took me a little longer to say it. but anyways, idk how to explain it he’s been super dry over text and distant. he texted me good morning but he’s not really being like he was. i’m starting to get scared that he’s not gonna try anymore cuz he “won” idk. i’m paranoid about that. like he was trying to get me to fall in love and now that he has, he doesn’t have to try anymore? i mean it’s only been like two days but he’s been so dry...it’s very strange to me. i’m worried. i don’t think he would do anything malicious, he’s a sweet boyfriend but then again i really don’t know.
