Should I contunie a relationship after she lied about her past?

I met a girl a month ago and last week we entered a relationship. Yesterday I found out she lied about her past. When confronted she made up another lie and after that I had to prove her another time that she was still lying. When I asked her to see the conversations that she lied about she showed me only a bit and denied to show more. I know that the conversations were from before we met. She stated that she was faithful to me the day we met and tbh she never gave me reasons not to thinki so. I was alone all my life and this is my first girlfriend. I can't trust her anymore because I know that when she is confronted with a lie she will still lie. I was thinking about still staying for a few months just not to be alone anymore and to finally be in a relationship because when I met other girls they said that the fact I was never in a relationship is a red flag.
