My ex ex, started to talk to me again just a mounth ago. Yesterday he fingered me. What does that mean?

Okay well, he's giving me mixed emotions! Just a few months ago we started to talk again and its not awkward at all but yesterday when we were hanging out with a group of are friends, he would always be by my side. Also that day he fingered me. Just a week before he told everyone he like another girl. Now i'm really confused because i kinda do like him now. HELP ME PLEASE GUYS AND GIRLS HELP. Thank you.
