My situation is a bit complicated with someone who I called a best friend and my now ex. I just found out a little over a week ago that she has been sleeping with my boyfriend for who knows how long, and I found this out through his phone with pictures and texts. He is out of my life completely without a doubt now but it’s her betrayal that hurt me the most. To make this even worse, she is engaged with her boyfriend of 6 years and she has me up as one of her brides maids. I have been debating between I should speak with her fiance and tell him, talk to her but how or just not doing anything at all. I’m really hurt and I feel so betrayed, to have lost two people who meant a lot to me is really just something I don’t wish to anyone.
