I'm finding it hard to cope tbh :(?

If you look through my previous questions, i've explained about this boy and us meeting up. If you would like to understand what i'm talking about more, please flick through my previous question and you might understand more. Moving on from that question. I was going to meet up with that boy, and we arranged to meet up last saturday. i asked him friday night, if we were still meeting up and he said "no sorry, i'm going somewhere with my friends i forgot sunday?" i was dissapointed but i agreed to sunday. Saturday morning he text me saying "i love you with all my heart." and stuff like that. Then we didn't text all day saturday. About 10:30pm i text him asking him what he was doing, he replied normally saying he was watching tv. Then i asked him if we were definately meeting up sunday. i didn't get a reply. So i thought oh well, maybe he hasn't got the text? So i was browsing bebo home, when i got home. And i noticed His ex's name and - "his name, i'm glad we're back together tbh ily." i clicked onto her page, and there was a paragraph about him saying how much she misses him and she was glad there back together. I showed my friend and she asked me for his number. She rang him up asking him if it was true what i had read. He said it was, she asked. So what about becky, and about what you've been saying to her? and he hung up. i asked him, and he used the exscuse of his friend, asking me out and his ex saturday had asked him back out. So he thought it would be easier to go back out with her. His friend sort of asked me out, but he's one of those guys who fancies everyone if you get me. After all he had said about him loving me, and he should have at least waited until we met up don't you think? Then i would have understood. But i feel used. I feel like he was just flirting with me to get back at his ex. I text him "see i told you i loved you more :/" he said "well you obv did :/" i'm heartbroken, i knew i would have liked him if i met him. but he had to ruin things =/ do you think he used me? =/
