Hes back form the dead can't he go back?

So I hung out with my ex the other day... and lets just say it was interesting. Let me start form the begging last week I got a text from him ( weird we haven't talked in forever) and he asked if I wanted to hang out. I'm thinking what the hell do you want to hang out with me for ( reasonable thought) so I confided in my best girl  for advise on how to handle this awkward situation. I told him we could hang out when I got off work to see what he wanted cause he had to be working some angle. Being the awesome bitch I am I went home after work to change and waited for him to text me about hanging out (making him think I forgot) which I was kinda hoping he wouldn't but hes a persistent one and really wanted to hang out. For some reason he wanted to meet downtown so of course I'm on time and hes late (typical boy). Here's where it got weird he took me to his house after we met up. I know where he lives we dated for awhile and I was there on numerous occasions but whatever. So we get back to his house and watch a movie and then I see why he wanted to hang out so badly. He has his arm around me and getting super close to me WTF!!!!! He was the one who broke up with me in the first place did he forget? I take it that hes lonely and realized what he has been missing but he will have to keep missing it cause I'm not going through that again but we can be friends.... yeahhhh friendsss.
