Is there something? 27m and 34f

ill be honest im falling for my co worker. I like her a lot. She finalized her divorce last Wednesday. Ive been working at this job for about 3 weeks. She started a week before me. I asked for her number on the third day of working there. She laughed and told me not yet. Me and her have already has really personal conversations at work. She has opened up to me about a lot of things, despite not talking outside of work. I make her laugh and whatnot to make the time pass. I honestly think there might be something there.

do I keep pursuing this or no?
