I need to know if I should trust her...

[Italogent]

Hi there,
I am a 36 year old male who is in a relationship with a woman of 34. We have been together for almost a year now and are very happy together, most of the time. Yet, somehow I can't help but feel sometimes in my gut, that I just can't fully trust my girlfriend. I wanted some female perspective on my situation as I know my male friends are biased.
Basically, to begin with, she's a natural flirt, and I am not normally the jealous or possessive type, but her body language and dirty jokes has put me in uncomfortable situations. I feel insulted somewhat but realise that she probably just enjoys the male attention, she is very affectionate to me and I don't feel unwanted so I gently mention to her that she is maybe giving off the wrong signals. This is also significant because she tells me often about getting unwanted male attention. I want to trust her and let her be happy but my gut instinct makes me wonder is there more to her than meets the eye. Actions speak louder than words and once or twice we have had minor arguments due to our different standards on loyal behaviour.
Just recently a serious red flag happened... Over the previous months I have come to know she has various male friends which she contacts from time to time, and I am ok with this, one of these old friends she has described as "extremely good looking", he contacts her sporadically, but she claims no interest in him....... I had told her of my plans to go to a music festival at the weekend and asked her along, she declined due to work responsibilities.... She had used my phone to log into her social network site earlier that day, and when I went into her account accidentally on my phone I noticed worryingly that she had sent a message to the "extremely good looking" friend asking him "was he around any time soon?".
The thing that disturbed me was that she sent the message to him at the EXACT moment she found out I would be away for the weekend, down to the minute. I don't want to be paranoid and jealous but it seems like the second she knew Id be away, she thought of him. Any feedback on this situation would be great, I would like some female perspective on whether or not I should trust her?
Thanks for your help

I don't know if you should trust her or not.... all I know is that if a man I was crazy about was concerned about my behavior, i would be examining it.

This is just my impression, it seems like you already don't trust her at all, and I couldn't find any factor to let you trust her in your text.
My advice is, just asking about it to her, otherwise you would never know her feeling. I know it would scare you, there's possibility to make her pissed off. But think about it, if you can stand to stay together with the concern for the rest of your life.

I suggest you hire a private detective and have her followed.
