I miss him

He told me he loved me all the time and we didn’t even make it to three weeks he’d find reason to argue with me but I still loved everything about him he was my moms first choice as well he had suspicions of me liking my boy best friend so I stopped talking to my boy best friend even though he said I could have friends that were boys and one day his friend made a inappropriate comment to me and I was uncomfortable so instead of him being mad at the boy he was mad at me basically saying I was overreacting and he was upset about me and my guy best friend getting in contact so I called him childish and then some time in he texted me he loved me and then he was telling me he had to talk to me and I found out he was breaking up with me and instead of it being simple he started segueing me just to have the last word but I still love him and cry about it constantly should I feel this way?
