Thank you so much guys.
We went out for some food and drinks last night and it went really well. I've been trying to be more assertive more masculine from what little I did read from the 3% book( planning a big read today).
However when we went to bed, I went to hug her( spoon style) and she didn't say anything, but literally did not even reciprocate anything back, just lay there and didn't seem interested in my gesture. So eventually I let it go and went to sleep.
It seems whenever a physical interaction or play by any sort by myself is initiated she does not seem to welcome it at the moment. Its so weird, it has never been like this before, we have had our ups and downs but she never has give me the cold shoulder like this. Its honestly like she has completely closed herself off physically.
Here is the biggie though, I know I shouldnt have but I read through her phone when she was in the shower.

. No guys seem to be involved but I did find a message trail to one of her friends.
She basically said to her friend that:
She never seems to be 100% sure anymore about us
Keeps thinking a lot recently about spllitting up/ not sure what she wants
Not sure if her heart is in it anymore
Mentioned the fact that I gave her a back rub and that im obviously "making an effort"
During this conversion, she said at the end that we will keep on trying and see what happens

.
I know it was a total scumbag move, but I know where she is it. It seems that I definitely need to work on my masculinity judging by the making an effort line?
She is actually on a night out tonight with her friend so I'm sure she will be looking to get back into the single scene.
My head says tomorrow I should just tell her its over and that if she isn't 100 percent we should be apart, my heart says otherwise because I am an idiot.
I think the thing that intrigues me the most is that there were several phases in the relationship where I wanted to split from her but didnt want to hurt her, it seems maybe like the shoe is on the other foot now. I find her more attractive than ever now, I know this is because potentially I may lose her but its bugging me.
I just turned 30 years and head ideals of settling down, getting married and having kids. I'm sure she did too, infact it was only a few months ago she was all over me ( sending me texts all the time) and initiating a lot of contact.
