My wife thinks she might be a lesbian

[Dyno]

I have been trying the 180 approach which is very hard to do as we have always spoken or texted one another during the day or night. Our whole dynamic has changed since she spoke of being gay. I still want to talk and text but have been holding my ground in the hope that it might be fantasy or fetish. When she leaves to go to be with partner it breaks my heart I try to just blow it off n just say ok and that's about it. But inside I'm dying and have to put on a happy face for the kids sake. I lost my temper on Monday after I got home from work I which I deeply regret showing that this is bothering me so much. After work I got home and my 4 year old was in my bed and had peed I didnt get upset with him but raised my voice in frustration which woke my wife after changing my son In raised voice and anger I expressed its bad enough that's she's been carrying on behind my back for so long now she just let's our son wet on my side of bed and that she has absolutely no respect for anything or anyone she apologized and we made the bed and went to sleep. Yes we still share the same bed it is real big but that's all we just sleep their which at first was tough but I don't feel I should have to leave the bed because it is her choice for D. I've since reverted back to the 180 and only accept calls or texts and only respond to ones that have true matters concerning kids.
