Should I still be with a liar?
So I've been with this girl for 6 months now.. We've had some problems where I didn't trust her, she then confronted me and said she wouldn't do anything behind my back... She showed me her messages and I saw she send guys x and to us x is a big deal (flirting) she said she won't ever do it again and I pleaded my heart out and she promised she won't do it again
So now she was on her Facebook account and she doesn't know I have it as well. She said to me if she can say hi to her friend (she says it's her big brother friend) and then I said sure.. She said to me she just said hi and then I said are u sure and I saw what she said to him (she said "hey big bro x") but she was lying to me again and I tried catching het out.. I then did but she threw a fit... She promised me she won't lie to me again but she did... What must I do?
