My crush said I love you to me in a text today. Should I take him seriously?

I love my guy friend and I think he's crushing on me but we're too chicken to have the dtr talk. We take a lang class together and he used to say I love you in another lang to me, but I told him to stop, unless he meant it, because he was using the romantic way and said he didn't love me romantically. I told him how to say I love you as friends but he just stopped saying it, except in English, like "love you", not I'm IN love with you.

Today he texts me about another class and closes with (romantic) I love you in that language, his nickname for me and ciao.

He's really shy and insecure and had told me he feels unworthy of love. He remembers everything I've ever said to him and quotes me on it a lot, so I don't think he forgot how I told him to not say that unless he meant it. Should I take him at his word, because that would be a huge step, since we haven't even kissed.

I am in love with him and I think he might be with me. We've been having really long silent stares every day and we touch a lot in little ways. He gives me the head tilt dopey smile stare a lot, like he's wasted or something.

Should I ask him if he meant it? I texted back I love you too, romantically, but he didn't answer and I won't see him until tomorrow. Should I just act normal and forget it?
