<human>: My wife [24 F] had been distant for a long time, paying little attention to me and playing games online all day. I found this suspicious after a while, especially when I would say "I love you" and she wouldn't say it back.

Well I looked at her phone and found she had been texting and sending naked pictures to one of the guys from her online game. I immediately confronted her, and she essentially blamed me, even though I do everything I can to be a great husband. 

I [26 M] work alot and also am a full-time college student, so she takes care of the kids while I work (from home). She didnt have sex with him, or actually meet him but I don't think that really matters. 

Anyway I made a list of what I expect, essentially she needs to explain herself and end all other relationships. She responded with a letter saying that "she needs time".

Can you give me the gist of the text in a nutshell?
<bot>: Am I right to expect her to make a decision right now? Should I even give her a chance to make it right?
