<human>: Can you provide a brief rundown of the text in within 3 sentences?

All of this is very confusing and a constant roller coaster for me. I have known her going on 7 years in total. 

All of this stuff started when she told me about an emotional affair with someone I worked with, Who was a really good frined of mine before this. After he was out of the picture(as far as I know) she went after an old ex-boyfriend from high school. 

Now when she talks about leaving and divorce she also talks about future plans to buy a new house together and even buy new rings for us. I feel like I'm being toyed with and really don't know what to do.
<bot>: ! Wife(F/21) of 3 years wants to leave after emotinal affairs and still talks about staying together at the same time.
