Is my boyfriend really sad about our breakup? (Guys opinion)?

During the time we were together he filmed me giving him head and he rubbed me telling me it was okay when I was apprehensive at first. He then posted it on snapchat. He is 21 and in a fraternity. He refers to himself as a ladies man. He constantly says im pretty under my pictures and posts pictures of us together. He thanks god for me being in his life and he says he loves me. When we broke up he starts posting that he is a failure, why must good things come to an end, and what would you do if you only had one day to live. He also posted that he was in pain and to pray for him. Then he posted humans are selfish because I think he found out I went my friends after we broke up. Then I hear he is calling me a brat to his friends behind my back. Is he sad and did he really love me?
