Yes I agree with the other posters here. Get in touch with some healthy self respect and put your foot firmly on the gas pedal of your own life. There are three main things you can do to stand for your marriage:
Don't file for D - unless you want to Don't date Keep the door open a tiny chink in the event she wants to reconcile at some point in the future
But I'm going to tell you this. If she is involved with OM, that is unlikely to happen any time soon, and you need to get yourself in a stronger place independent of her.
As others have said, don't SAY anything to her, just start doing some healthy things for yourself. You are moving forward with your own life because she is someone else's girlfriend right now. You are no longer in a R with her.
Now, if she asks you - do you want to D - you can tell her no, that's not what I want. But certainly don't be willing to put YOUR life on hold while she tests out life with a new partner okay?
So - enough of her...let's leave her be for now. We are on the cusp of a new year and I'd like to see you thinking about some early goals for yourself in 2017 my friend.
