How to know if I should give a guy a chance?

My guy friend of a year confessed he like me and so did I. He’s been acting like we’re in a relationship but not committing. He says he’s subside because we have different denomination. I don’t see an issue because we have similar values and same core Christian belief. I really like him but I don’t like being stuck in this weird phase. How do you know if you should just move on or try to make things work?
