Should I end my relationship with a girlfriend who keeps lying?

So this girl has story of cheating, she told me she dated 5 guys at once, she told me she dated all her brother's friends, but i did not care since it is part of the past.

but while dating, we had a fight we did not talk for 4 days and during that she met a guy for lunch and she told me it is lunch meeting.

after that she allow a man to driver her from Work to home and she told me he is a friend and he passed by coincidence.

and she accepted someone's invite to do jetski and she told me i am home and later on she told me he is a friend and i was only afraid of your reaction that is why i did not tell you

after each interaction she cries and beg me to forgive her but then she do the same thing again,

what should i do guys?
