Can you ever fall out of love?

I was with a guy for three months we broke up and got back together and were together for a year and two weeks. We broke up last Feb. I still loved him and I wanted to be with him. What ever I did I couldn’t get over him. 6 months later we hooked up. I thought he might have feelings for me but after that night he ignored me. 2 months later we hooked up again and I was honest with him I told him I still loved him and that what we were doing ment more to me than just hooking up. After that things were great again. I thought we might have a chance to get back together. 1 month of things being great and then he started to avoid me agian. I was confused and I asked him what was up. He said I need to get over him because I can do better than him. He kept telling me I make him feel things that he doesnt want to feel. I have cared about this guy for so long. It doesn’t help that he’s my best friends brother either. Now I’m with someone and I’m happy, I feel like I’m over him but I really want to know. Did I stop loving him or will I never stop? As soon as I’m not with this person will I feel like I still love him? Can you fall in love again even if you have already given your heart to someone else and thay didn’t want it?
