Get the hell out of there. One lie: maybe acceptable. But repeated lies like that and then deleting the text messages to try and look innocent when she'd been caught out is unacceptable, and will only continue happening. If she really loved you she wouldn't be contacting and going out with these other men; she'd be focused on you. You deserve better!
