Trust issues

Hi, I’m not sure how to say what I need but I’ll try. I’m really struggling right now with my relationship. The woman I’m in love with is struggling to trust me. She has PTSD and other trauma issues and trust is huge for her because of her past and being mistreated. We’ve been together for 6 months ish. I was originally still living with my ex and it was a really crap situation. I needed my own space and so asked my mate who lives behind me if I could rent his spare room. It wasn’t very big and some times I stayed on the sofa at my exs but only when she wasn’t around. I thought I explained my situation to my partner but she told me I had lied and hid things from her. I admit I may not of said anything and wish I had. I’m moving out in the new year and told her that too. She accused me of never being at my mates which isn’t true and says she can’t trust me. We’ve spoken since and both felt so horrible and down about it all. I went over to hers and we had a drink and laugh and I stayed over and she thanked me the next day saying we both needed it. Part of me thinks she wants to work this out but another is thinking she’s making me wait for her. I’m so confused and lost.
