please don't judge me

My Ex Boyfriend and I broke up 3 months ago, he recently has another girl. I still love him.... we still talk but he calls me his best friend now and I don't like it. Yesterday he came over my house to hang out and I was sad to see him texting the other girl and you know not giving me attention, and I know he's not my boyfriend so he doesn't have to. But I got carried away... he was tickling me and he came close to my face and I kissed him and pulled away and said sorry and he gave me that look and pull my face and kissed me all I was thinking about was his new girlfriend... I want him back, so bad, but I haven't told him this be cause he wants to be just friends. What should I do.. I need him
