Well, coming from a girl who has had a Complicated relationship. All you really need to do is be open with her. Tell her that she can trust you, and be open about yourself.
And ask yourself, if you can't trust her than there is no way she is going to trust you.
So just be open, be willingly to trust her and make sure she knows your there for her and over time she will open up.
Why couldn't you trust one.
you keep in touch with her and show her how much you love her threw the phone.
Trust her.
it means you do not trust your girlfriend.
completely
TRUST:)
there is very little you can do.... there is no quick fixes to lack of trust...the best thing i suggest is stay faithful and truthful to your girlfriend and she may learn to trust you again.
A girlfriend can trust her boyfriend by asking him if she can or be testing to see if she can. A girlfriend can set up some simple experiments by saying things that she already knows is true and then testing to see if her boyfriend is honest with her. Also, trust takes time and if the girlfriend has lost her trust in her boyfriend then he's got to get it back. Or he will be costing their relationship, big time.
Trust is the key word
Show him that he can trust you.. Show him that you're only there for him.
then its not worth it
if she is a trustworthy person
