<human>: Give me a shortened version of the text

In the past week my life has changed very much.  I have been dating my SO for about 3.5 years, we have lived together for about 2.5 of those years.  She has a 7 year old son who was 3 when we started dating, so it was the 3 of us living together.

A quick rundown of what has transpired.  I had noticed that lately she was very distant from me.  I asked her about it and if there was anything I could do to help?  We talked through it and I was told it was a combination of stress from all of the schooling she is doing as well as trying to balance a job and a home life.  

We did this over brunch.  As soon as we were leaving from brunch she then tells me she has something else to tell me.  My heart immediately sank as I have seen to many stories with similar situations.  I thought she was gonna tell me she cheated on me.  But she proceeds to tell me that there was a guy from before me who she never really told me about and that she has never really gotten over him.  They had recently started talking and told eachother that they still have feelings for eachother.

Since then  I have watched my love life just disappear from in front of me.  She is now staying at her moms and I am pretty sure my relationship is over even though neither of us has really said it.

I am really heartbroken over all of this and am now thinking through our whole relationship trying to figure out if it was all genuine or not.  I really just need help with how to cope with all of this.  I dont do to well with things like this and could use all the help out there to make this a less painful process.  

Thanks you reading this and you help if you have any advice.
