Would you leave your boyfriend for this?

So me & my boyfriend have been together around 3 years and I woke up to a message from a girl saying that she was out and my boyfriend brought her a drink they exchanged numbers and he phoned her a lot asking her to go back to his hotel room she showed my screen prints of his number and how many times he phoned her etc. would you leave him? I’m really stuck
