My(26) girlfriend(25) lied about where she was going can it be redeemed? Relationship length just under 5 years

I should mention that we live together and we weren't having any problems in our relationship before this. So a few weeks back my gf said she was going to stay at a girls house for a girls night out. But I went on to our computer and went onto Facebook. Not noticing it was logged into her account as I don't use Facebook often I saw I had messages so I checked them and found out she was staying at a guy from her works house. She assured me nothing happened and the only reason she didn't tell me is because she thought I'd freak out if she told me the truth but I explained if she had just told me the truth it wouldn't have been as bad. So on halloween we were supposed to be going out together with people from her work. She told me not to come for a long reason I don't feel is necessary here. But she was supposed to be going to her parents afterwards and staying there for the week. I've now found out that she is staying at his house again. She is refusing to reply to me now. I've been calm and basically said I just want to discuss it and to understand why she is lying to me. All my friends and my family are telling me that I need to end it with her because she's just showing me no respect at all.

Tldr; girlfriend lying about where she is staying on 2 occasions now and is staying at a guy from her works place.

Can this be redeemed at all? Does anyone here believe there is a reason good enough to justify this?

Thanks for all the replies, the answer is resoundingly no. This is gonna be tough man. My friends all stay so far away from me now. Not got much in the sense of support but I'm sure they will do their best.
