I don’t know what to feel or think

I’ve been talking to this guy for the past five months and we’ve also been fooling around he took my virginity too I like him and I trust him I feel comfortable with him but something in the back of my mind isn’t all the way in for him on Wednesday we were making out and I was kissing his neck while doing that he says to me “I think I love you” and I stopped and looked at him he looked really serious and said “too soon? Did It ruin the moment?” All I said was “no it’s okay I’m sorry I don’t know what to say” and he said “it’s okay keep going” and when we were done hanging out and I drove him home it was so weird I tried to be regular about it like nothing happened but I don’t know I’m scared I’m truly scared I’ve never had a boyfriend nor had a guy actually interested in me like he is this is all so new to me should I take this seriously or am I just over exaggerating about this. Help !
