HiCustomer Thank you for asking your question on Just Answer. By the way, it would help me to know:
-What are your ages?
-How long have you been dating her?
-Do you have a reason not to trust what she says?
-Is she an honest person?-Could you explain your situation a little more?Thank you again for trusting me with your problem. Please reply as soon as possible so that I can finish answering your question.
Other than the incident where she was sleeping, she did lie to you about her friend getting into an accident so it's not totally you but you need to get her more trust until she shows you that she doesn't deserve your trust, she just hasn't given you reason to not trust her other than saying her friend was in an accident maybe she told you that because she thought you would get angry and didn't want to cause a fight. She is young even though she acts mature she isn't ready to be tied down and have someone to answer to so maybe you should try letting her have her time with her friends and call her in the evening and if she isn't home maybe you should allow her that time. Yes, you have seen more than her but you have to allow her to make her own mistakes and learn from them just be there for her and show her that you trust her even if the urge comes over you not to trust her.
She may be scared but maybe she just doesn't want to have to answer to someone after having to do so for so long she wants you to be that cool person she met and care about and she doesn't want you to change and maybe she sees sign of that other relationship in you and this is what is pushing her away. Even though you know you won't be that bad she doesn't' know that and is gun shy now give her time she will come around and see that you are NOTHING like that other guy. If you have anything to add click reply.
I would just chalk it up to her being in the middle of doing something or maybe she doesn't want to answer it at the time like you said she gives you no reason not to trust her so maybe she just doesn't want to answer the phone try leaving her a message and asking her to get back to you as soon as she hears the message or receives the text message. She will mature and learn the more the two of you are together if you have noticed an improvement then it could get even better as time passes.
