I need some help

Hi I’m gonna pour myself out here. A couple years ago I fell in love with this boy and I liked him so much that I saw no flaw in him (there were many) and wished to be his so bad. We dated for 11 toxic months, my first love, my first kiss, my first time feeling so much passion for one person. But he treated me not so good but he also treated me good and I loved him and he broke my heart and I was so happy ab it at first bc I had been suffering with his lies. But then I cried and cried and cried. 5 months after we broke up I meet this other boy from cross country. He’s cold at first to hide his feelings from the team but eventually reveals himself to be incredibly loving when he falls in love with me, we are dating, he tells me how he feels and his dreams about me and it reminds me of what I felt for my ex. But the dilemma is that I like him so much in my head but my heart feels close to nothing. I miss him I want to hang out (but get a little bit uneasy before he comes) I like the things he says. But I feel no passion. No fire no butterflies. But he’s amazing and supportive and has big flaws too but he’s a great boyfriend. And I don’t want to leave him bc I know that I don’t want to see him everyday at practice for the ne dat few years and I don’t want to see him w someone else, but I don’t know what I’m supposed to be feeling bc I do not feel much, my mind loves him. But my heart longs for more feeling. Please give me your solemn advice. I never want to break someone’s heart especially as a mistake . I don’t knwo what to do. Do I give it time? Am I wasting my time?
