Feeling paranoid about gf trusting another guy over others

[Miasmata]

If you disgust her simply because you weren't okay anymore with being hidden or otherwise mistreated, then she's not the right one for you. Respecting someone's boundaries and conservative nature is one thing, but that still doesn't make it okay to be treated like second rate. You deserve better.

I remember your old post:

Out of the blue, I randomly asked my gf if she would accept me and take me back if I cheated and slept with another girl. My boss is quite good looking and I told her about it. My boss is married. I didn't mean to test her in any way and I just wanted to know how she would react to it. To my surprise, she said " I would accept you back depending on how it happened, its not a big deal.. I have a soft spot for you". I have no intentions of sleeping with any other girl. I was completely shocked and disappointed. Why would she accept someone who slept with another girl? Does that mean she would do the same? She does live with a male roommate, not in the same room but same apartment and she tells me he's married. Now I have so many doubts about her. I can't trust her. I don't know if its my insecurity or am I thinking too much.
My whole view about her completely changed in a day and I don't feel like I should take her seriously anymore.

It seems that the two of you have had some issues with trust back and forth. (Example: She said she doesn't trust me )

I can't say this enough: trust isn't established overnight. Trust is built over time. Being honest over a duration of time helps to build trust.

I would autopsy this relationship and figure out what role I played in the relationship becoming the way that it is. What led you to this point? Here are the relationship autopsy questions I would ask myself.
