Umm...

I have been talking to this guy for MONTHS. He said that he loved me and wanted a relationship with me soon. We’re both out of school now but we met in high school. I’ve always liked him but I heard he was always talking to someone else. Well now I asked if I was the only girl he was talking to and he said “yeah something like that”. Okay first of all he’s definitely not a dick or anything he’s soooo nice 24/7 and he doesn’t seem like he would have a bunch of girls but idk anymore. What does “something like that” mean? He asked why I was asking and I told him I wanted him all to myself and he said I would get that soon. Is he implying that I’m not the only one? I asked why not now and he said I want to make sure you’re not the only one?? Yeah I mean obviously there is someone else. Should I run for the hills?
