Wife is having an emotional affair

[Alan A.]

So more recently She is still texting OM. Most days they go until around 2AM. Today I tried to just ignore it which worked at first but got harder as the day went on and every time I saw her reach for her phone I hurt more and more and every time I want to ask her to stop texting him (I've resisted so far as I feel it would make her feel I'm trying to control her, is this the right move?). By bed time I cant sleep because I'm just to distracted/worried. here's a weird thing though, she still wants to hold hands, hug, cuddle, and kiss(not passionate just a quick kiss, sometimes a few in a row). I'm not sure how to feel about this, is it just routine or does she still like doing those things with me. Should I allow this? I have been thus far. Also I when ever we are out together I always make it a point to open doors for her (including the car door) should I continue this? I'm really worried it's going to turn into a PA and I know I would not handle that very well. Any thoughts on the situation would be greatly appreciated.
