I Am So Done

Honestly, yesterday at the church group meeting, we had a birthday party for one of the members who is on a wheel chair. The guy I like didn't give me much attention to me as he normally does. I am not being selfish, I know it was a GROUP meeting, but let me explain before someone judges. I sat next to him to eat pizza, he talked to everyone else around him, he kind of scooched out to sit closer to someone else. He wouldn't include me in conversations, and he would only give short answers to questions I ask. After he finished eating, he got up and sat next to this girl who is a guitarist and started joking and playing around with her. When we sat back in our circle, I saw him smile at her across the room and she smiled back and nodded. I have no idea what is going on, but he kind of pushed me away to talk more with her. He gave her the longest hug when we all greeted each other. After the meeting, my friend stayed with me until my dad picks me up. The other guy left already to the place where they meet up thinking I would go but I never go. Basically, he didn't say goodbye. I've been talking to friends and they are trying to help me out. One of them theorizes that he is leading me on. Why? He kissed me for the second time after I said no, the next day he asked me on a date, I said to ask my parents since I thought we were heading to something serious, he said he would but he still sees this as friends. I am so angry, so done, I am thinking of talking to him, but I still want to find out if he actually is leading me on or it is my jealousy over that girl.
