.Yesterday she went to some guys house that likes her. She originally told me she was at her moms house. I Found out she was lieing because her phone awnsered for a split second and i heard a persons voice that was not related to no one at her moms place so she had to explain.Her Explanation was she went to go play poker at a friends house Before this she was suppose to come to my house and she never came until 2 am after I found out she was at that guys house .I went to sleep at 6pm and she was calling me at 8 didn't wake up until 11:45 her excuse was that i didn't awnser the phone that's why she did other plans . I previously told her i was going to take a nap she clearly has the keys to go into my apartment because she didn't come i woke up so late . I don not know if i should keep going out with this girl or what i should do .? I have been goin out with her for 4 years
