He just told me he's been talking to other women...

I've been dating this guy for several months now. He told me he loved me about two months after we'd been dating. He just told me that he's been talking to other women since the beginning. I don't know what to do. It's 3 am where I am and I feel like I need to talk to him. I finally got him to talk to me for a bit on the phone. He is ashamed of himself, but he's not coming to talk to me until tomorrow. I don't know how I'm going to be able to wait that long. Part of me still loves him, but other part of me is questioning everything.
