If a guy I have been meeting and hooking up with starts to leave me on delivered even though he is active does that mean I should give up? I like him?

a couple of weeks ago this random dude adds me on snap, a few days later we meet up and hook up, after that we started to meet a lot more, spend hours just talking to each other about so many things and we discover we have a lot in common. On Snapchat he always responded right away too. He told me many personal things like how recently broke up with his abusive girlfriend of 3 years. We really clicked with each other and I really started to like him a lot. I met him the last time around 1 and a half week ago and he has become more distant and does not hint that he wants to meet up. He is starting to go online on snap and not even responding to me but to others. I really don’t know what I should think of this, is he starting to lose interest? Yesterday I asked him if he wanted to meet up, he responded with “I don’t remember if I made plans with my friend I will let you know later” then he left me on delivered for 5 hours and at 1:30 am when I was asleep he said that his friend had made other plans. I really don’t want to give up on this because I really like this guy but is that the right thing for me to do? Should I just delete him from snap and forget him? I don’t even know if he is meeting other girls.. ah this is really a difficult situationship

He added me first from a dating app where he later added me on snap.. we did talk for a few days before we met up. What is confusing me so much is that he was always telling me how much we clicked together and I also met some of his best friends
