Guy Problems

So this guy randomly texted me and he's one of my ex-friends ex bf. So he decided to text me and I think he likes me, but he doesn't know how I look like. Because I've never sent him any kind of pictures. He's really nice and sweet but idk if this relationship should go further. I don't know him in person and I'm nervous to actually meet him in person. He's never said anything about it. I've only been talking to him for a few days. He's a year older than me. Also he says I'm pretty but I haven't even sent him a picture nor seen him in person. He always sends me selfies, don't worry not those types of pictures. I kinda like him and idk what to do!! Help me, and thanks for your time!💘
