How will I know a Christian guy is just not interested in me or is just expressing boundaries?

Christian dating related. We flirt and spend time together at work but he hasn’t asked me on a date e. g. in the evening or at the weekend or outside office hours. We went on one lunch date during work but that’s it. We have been talking for 2 months. What’s his strategy here or is he just not interested?
