Could he be dating her? I'm lost?

[marc dello]

I've known this guy for three years and we've had an on/off relationship. This summer, we both graduated and he moved back to his hometown. I decided to keep in touch with him and I traveled to see him twice. Both times he had wanted to be physically close but I felt he was emotionally distant, we didn't do it.

I thought it could be this girl who was regularly posting friendly comments on his facebook wall but I never asked him anything. As I said goodbye to him, he said he didn't want a relationship right now and said we needed to take a "break". I cried but I understood because I'll be going soon to Thailand for six months and he will be traveling too. As time passed, he initiated a conversation but he would take time to reply to my texts.

This is why she wrote on his wall: "Today has been an amazing day. It has consisted of going on a mountain adventure, a near death experience on a rope swing, making candles, being tricked into licking a lolly pop made of soap and watching amazing films. I have missed hanging with **** so much ♥"

He added her this summer but I went through his timeline and I noticed he was friends in 2007! he hasn't told me anything on the phone, just friends and work...could he be dating her?
