Is my ex still harboring feelings for me?

This is kind of a follow-up question to my other question so it might be helpful but not necessary to read that one.

As some of you know, I was experiencing a lot of anxiety over potentially seeing an ex boyfriend that I still have affection for over Thanksgiving break.

The day before I went back to school, he messaged me on Facebook and we had a really nice chat that ended up going for a few hours. We kept it light for the most part and didn’t talk about the relationship. Right before I sign off, he asks what I’m doing that night because he would like to see me before I leave…

Long story short: he comes over to my house around midnight and we end up just sitting in my room talking until about 6:30. It felt really good actually. We laughed a lot and relived some good memories of our time together. We still didn’t talk about our relationship much but he did disclose that he’s not happy with his girlfriend and wants to end it with her sooner rather than later. Because we’re both technically with other people we sat a respectable distance from each other and didn’t really exchange any physical contact but there was a lot of meaningful eye contact on his part that indicated that the attraction is still mutual.

Right as the sun is coming up, I walk him to the door to say goodbye. He extends his arms for a friendly hug which I willingly oblige but he does something unexpected. He pulls me in very close to his body and gives me 3–4 kisses on the cheek and neck which I also do in return. He then kisses me perilously close to my mouth and holds my face a mere two inches from his and looks into my eyes as if he really wants to kiss me if I would give him any indication that he could. Not wanting to do something transgressive to our significant others, I don’t kiss him on the lips despite really wanting to. He says that he would like to come down and see me in the city sometime soon and says goodnight.

After he left, I couldn’t sleep a wink for not being able to process what exactly happened there…

The next day, he asks if he can give me a ride to the train station which I let him do and our goodbye was similar to the one the other night. (tight embrace, intense eye contact and more kisses on the cheek that don’t quite go ‘there’)

Today he’s been all over my Facebook account, messaging me to chat and ‘liked’ a song I posted on my page that reminded me of him. (Not sure if he knew that)

I haven’t been able to talk to my friends about this as I can barely process it as it is. I know that it’s unlikely we can ever be together in the near future because he’s across the country but I’m trying to make sense of what’s happening between us. My ex is kind of a non expressive, shy person so he can be hard to read. What do you think he’s trying to tell me?

And yes before anyone brings it to my attention; I’m aware that I sound basically 14 years old right now. :-[
