David,
I’m sorry to hear about your situation. I understand it’s been about a month since this occurred so I hope you’ve gained more ground in this. From the sounds of it shes scared to let someone in because of something in the past that has happened to her. This is quite common with a lot of people and can be very frustrating on the receiving end. I’m currently in a new relationship now where I was the one who was closed up, what my girlfriend did was stayed consistent with me always reminding me she’ll never hurt me and worked as hard as she could to gain my trust. But, in the end it all takes time. Remember Rome wasn’t built in a day, neither are relationships. Keep at it man and tell me the outcome!
