Soo confused

So I matched with this guy on tinder and we had been talking and everything and he told me that we was looking for a relationship and to kind of take things slow and he hoped I would want to do the same since he thinks I’m really attractive and he wants to get to know me and i said yes and we chatted for a bit longer about ourselves and such and I went to sleep. I wake up this morning to see if he messaged me maybe after I went to sleep or whatever and I find that THE BITCH UNMATCHED WITH ME!!! WTF!!! I cannot even remotely figure out why that happened or just anything any ideas??
