Best friend and my Ex
Ok so heres the deal. I just found out that my best friend has slept with my Ex. I dont still have feelings for her but i dont see that thats the point. Me and her had a very serious relationship, we lived together for almost 10 years and have 2 kids together. We have only been split up 3 months and i find this really disrespectful. I dont care who she sleeps with as long as its not him. Am i wrong to think this, Is This Normal??
