Search Results: letting her know i am interested

Recently I sent a random Snapchat to a guy I've known over the past few months, and he responded pretty positively. Neither of us ended up letting the conversation die, so we've been Snapchatting continuously for over a week. Sometimes the messages are random/kinda meaningless, but we've also gotten deeper, talking about our pasts a bit, our likes/dislikes, asking each other about our days or some slightly deeper topics, etc. We both make an effort to ask questions and keep the conversation going. We bonded over a love of animals, and he offered for me to come see his dog whenever when we're done with exams. Two days ago, I told him I was getting dinner with some mutual friends and invited him but he wasn't feeling it, but then he said he'd be down to get food next Tuesday and to just let him know if I wanted to go. We Snap throughout the day, and he responds in an hour or less. If he stops responding at night, he'll Snap me the next morning and tell me he fell asleep and then continue the conversation. Last night, he told me when he wouldn't be able to Snap for a while because he was going on a long drive but that he'd message me after (which he did). After Snapping for a while I thought his responses were getting a little short so I didn't reply, and he ended up Snapchatting me again telling me goodnight and that he'd talk to me the next day. Sure enough, he sent me "Good afternoon!" today and then we've been continuing our conversation.

Is this guy being friendly or showing potential interest in me? I'm really glad to have him as a friend, but it'd be cool if it led to something more, and it seems like he is showing some level of interest.
