I have started reading "No more Mr Nice Guy." Robx, I have nominated you to be one of my "Safe Male Friends" I am assuming you are male. If not, you put on one hell of a show. So, I am suppose to say what from my childhood helped in giving me the "Nice Guy Syndrome", which I am not yet convinced I have.
Really, my childhood was pretty normal. I actually had a pretty good childhood. But my parents did live a lot of their lives through us children. They were always bragging about our accomplishments to family or friends. It was something I really hated. Not sure what that would have to do with my current sitch, but the book said to share it with you.
LOL! Yes I am male, No I won't be taking pictures of the undercarriage and emailing them to you for your personal verification process - just take my word for it LOL!
As for being a safe male friend, safe is very subjective ;-)
No more Mr.Nice Guy is a good book, read it.
One more piece of advice, every interaction you have with her, you seem to expect that your current situation should just 180 and you should have solved this by now and unfortunately that isn't the case. It took alot of time to get you into this situation, it's going to take you some time to turn it around if that is your eventual destiny in all of this.
Remember you can't control her or her actions or her responses or her reactions. When she says something and she appears cold, distance, sad, angry - that's all her and you can't do anything to change that or control that.
I remember reading your response about her leaving a voicemail about people coming over and it being "cold", that may suck but it is what it is, let it be.
Control how you are, that's all you can do, be a great father, you definitely have control over that.
Remember what we have mentioned about "dating" or "social interactions", seriously the sooner the better if you want to get her thought process changing in a way that shows any of this as her loss.
You will be ok, regardless of how any of this pans out, that much I'm sure of.
