She reaches out to touch me and I can see light in her eyes but at the same time I know she is texting him right in front of me or going to the bathroom to do so telling him of her love for him.
I would recommend that you start with this. ^^^ Time to learn how to establish (and enforce) a simple BOUNDARY:
"I hope you aren't texting another man right in front of me. That would be incredibly disrespectful to me and to our marriage. I can't force you to remain married to me, you are a grown woman. But I damned sure aren't going to have you text your boyfriend right in front of me, from inside our marital home. If you want to do that, you can take it out in the yard."
