Seeing a girl who's unstable
I'm seeing a girl now who admits she's got problems sharing herself emotionally. She's got a fortress up because her previous relationship years ago ended horribly with the guy cheating on her. She told me she's become extremely independent and doesn't know how to be a really good girlfriend. I'm leading the relationship relatively well and I think I'm doing a good job of keeping things moving. She's definitely physically comfortable with me and I know she likes me in return. Only issue is that she still occasionally pulls away suddenly without being able to help herself. She admits she's a tomboy so sometimes she's not always acting like a warm woman. I'm sure some people would advice I keep a steady pace and work things out with her. My issue is am I wasting my time on someone who's going to be like this for extremely long periods? Is there ways to approach this issue? I already talked to her about it and said I'd be supportive. My friend thinks I might be investing my time into something that will be hard on me.
I would appreciate any input especially from those who are similar or have been with those types. Thanks.
