Don't know what to do and need some advice

So I've been talking to this guy since June and we've grown pretty close. He wants to date but I'm not ready yet. In October he told me he loved me and wanted to spend the rest of our lives together and he would wait until I was ready. Well I just found out that in November he was asking other girls for nudes and sending them back. I don't feel like I want to pursue a relationship with him anymore because I feel that if he loved me like he says then he wouldn't be reading with other girls and boys, while he says he loves me and is apparently straight. Am I overreacting?
