There is this really sweet girl I've been dating for around a month and I want to get closer to her and let her know she can trust me. I think she has some trust issues because her dad left their family when she was young. She has no personal relationship with her dad. He lives in another state and she isn't even really sure what he does at his job. She is really shy and quiet but she's actually starting to open up and get comfortable around me. Any advice on how to treat this situation? I want her to know I'm a sweet guy she can put her trust in and open up to me more.
