Either he feels it or not. He first said he loved you, and now he doesnt. I dont know. It sounds like he is unsure of his feelings. Chemistry is a huge part in a relationship, thats were the passion comes from, if theres no chemistry, no spark, than it might be dead in the water. You cant force someone into feeling that way. Its either there or not. I met a man once, and it was instant chemistry, I felt like I was on fire. Its been rare for me to feel that way about anyone. Its only happened twice so far, and I am not to young. You can try to get a spark going by doing things that he likes, but if he says he doesnt love you, I would think that would make you not want to. You know in your heart if hes being honest about his feelings, and go with your gut feeling. Hope it all works out for you two.
