Heart broken:(

I can't stop thinking about a guy who I've been seeing for seven months. We weren't bf gf, more like friends with benefits even though it felt like we were a couple. Few days ago, we were on the phone and as usual he'd talk to me as if I'm his girl. That same day something was telling to go online where I met him and look him up. There he was, on a dating site looking for a relationship. That hurt me so much. I confronted him and all he said was "K". Not even I'm sorry. I don't get men. Why would he waste 7 months travel an hr to see me and spend the night when he could've easily had someone else who lives closer to him. (Basing that strictly on his looks) So, confused. That same night he got rid of his profile. Why? So sad and heart broken.
