Help me.

So I met this guy through my cousin and started texting him and lately we've been texting everyday. But recently he just stopped answering me. We havent talked in about 2 days and the last thing he dicho to me was "hey :)" so he didnt give any signs of not wanting to talk to me, I'm really confused and wondering if it's right to be freaking out. I really like him but he told me he likes someone else :( Can anyone help me please?
