I found it interesting that your wife was berating you for not immediately responding to her texts. My wife likes to drop off the radar screen at times, but often scolds me for not answering my phone promptly. Sometimes I don't have it with me, or I may just have the ringer turned down. She likes to try to make me feel that I am not dependable because I don't immediately answer her. My job is to let her know that I am not obligated to even carry a phone with me.
I'm not sure why your wife expects you to be available to her upon demand. While she's carrying on another relationship? Only a fool would be available!
Your wife sounds like she's just using you to fix her problems. She's having fun with her other guy, but knows to call you to handle her day to day difficulties. I'd restructure your role with her if I were you.
