Should I stop talking to someone I know is not my type?

So I recently met someone who is really nice but deep down I don't feel any real chemistry with them. I'm still kinda stuck on my past person who I don't plan on going back to but yeah. I feel so shallow bc this new person had been nothing but kind and there's no reason for me not to give them a chance. Maybe I am shallow but I guess I can't help it. What should I do? I asked him to send more selfies of himself so I can see more of him and he said he would do that but it's been a day and have received any pics, it's like he changes the topic to something else instead.
