The wife and I have been married 7 months now. It hasn't been a great relationship, but it wasn't bad, either. Long story short, my wife has some health issues that prevent her from working. I understood that coming in. Problem is, she refused to take care of home while I worked to take care of all the bills. That caused me to be a bit unhappy. Fast forward to 3 days ago, I find messages on her laptop between her and some guy and the topic of the conversation was sex. Apparently, he wanted to come over to our house to visit her for sex, but she wasn't really comfortable with it. She went back and forth between, "We'll do it later" to "I'm sorry I messaged you and I wasn't trying to lead you on." This is some guy that she knew before she met me, so I know they have a history together. The trick to this whole situation is that she's pregnant with my child. She said it was a stupid mistake that she made because she felt like I didn't like her anymore because I seemed to be mad all the time. I'm pretty sure that she didn't have sex with this guy, but I'm wondering how I should move forward. Is this red flag from her major enough to seriously consider divorce?
