Will he stop liking me because I said this?

How long have you been together? It really depends on the duration of the relationship. However, usually that may put your relationship in a weird situation. I said that early once, and it was weird. However, it varies. I would suggest, it's best to talk it out with him, clarifying things that you don't LOVE LOVE him, but you really like him, adore him and just think you want to reveal it in case something bad happens. It was silly, that's all. See how he reacts, if he really likes you, he's serious about relationship, it may not be a big deal. However, if he makes a big deal out of this, he may not be the one. May have to let him go. Hope it helps. Thanks!
