Am I the problem or is a red flag?

Been seeing a girl for about 2 months now, about once every week. She gets upset at me saying I'm not committing to the relationship. We aren't exclusive but I haven't really dated anyone else during this time. But she feels like I'm not trying to spend time with her. She said that I'm pushing a good person out. I've heard this same thing from a toxic ex before and it has me concerned. I know I have commitment issues, but is it something that I need to reevaluate myself and try to commit to this girl or is this a red flag?
