Broken Heart

There was this guy that I was extremely interested in. He claimed to be interest in my as well. He would always want to hang out with me and I loved it. He said he was interested in going further with me. Things turned for the worst in the end. We have a mutual friend and I remember he would tell me to be careful friending her. He said the she was “emotionally unstable and young” and she was “trying to get with him and wanted him” he kept saying he wanted to hang out with me and missing me. So a few days after that he invites me over to watch a movie together. He keeps telling me how much he misses me and all and hates when I leave. During that time together I notice he constantly on his phone. I don’t snoop so I leave it alone. Him next to me I see that he is literally texting out mutal friend sexual and lovey dovey stuff. I see this because he is showing me something on his phone and the text pops up. I don’t say anything about it either I just keep a mental note. I wanted to wait to see if he will be truthful with me.
So days go by and I see him again lovey dovey on her social media dedicating songs to her and all this. I don’t have social media myself but my best friend saw it and showed me. I was crushed. Like both of them are being so fake to me. He sat there and told me “negative” things about her and of course told me not to friend her anymore because she would get on the way. Smh. She was talking to me about him like he meant nothing. I feel really played. He doesn’t even think I know anything. He is still trying to spend time with me. He still reaches out to me. And she does the same. Like why play me like that. I am a genuine person and there is no need to play with my feelings like that. If you wanted her that bad don’t speak to me about her in a negative way. The whole time we were hanging out he was talking to her and telling her the same sweet nothings behind my back. He the one who approached me on wanting something more. I let my guard down and all. Smh. I haven’t even been intimate with this man and it still cuts deep. I feel my time was wasted. They both were fake to me. Why he still calling me wanting to hang out if he is a lovey with her wth!!! This shot my self esteem down big time. Please help me.
