I don’t know you, but I feel an obligation to share some things with you. You may know, you may not, so do with this what you will, but I needed you to hear from me. There is really no easy way to bring this up and no way that I can make it sound better. Looking at the few pictures on your Facebook it looks like you and S are still in a relationship. I used to work with S and through that is how we started somewhat of a relationship around February of 2015.  A couple months into that I heard from some people I worked with that he was engaged with a child. I asked him about it and he did say he had a child, but said that you two broke up. I trusted what we told me and assumed that you two were co-parenting without being in a relationship. By May of 2015 our relationship became intimate and over the course of a year or so we continued to see each other. In June of 2016 I found out I was 12 weeks pregnant with his child. When I told him he said he wanted me to get an abortion, when I told him no he said he had too much going on and that he wanted nothing to do with the baby. I have not talked to him since.

The reason I am telling you this is not to spite S or you. I am telling you this because I simply think you deserve to know. If our roles were reversed I would hope you’d do the same for me. I want you to know I truly had no idea you were still with him. If I had known I never would have gotten involved.  The only thing that prompted me to find you was because when people at work found out that I was pregnant they put two and two together and started to tell me things about S. Seeing that you just had another child while he and I were together made me feel awful. Although he lied to me time and again to keep this part of his life hidden from me, I never meant to get into the middle of a family. So, from the bottom of my heart I truly am sorry for the part I played in this. 

I mean no ill will to anyone, I just simply think that as the mother of his children and the woman he plans to marry, you have every right to know that he was not faithful. I think you and your family (if you chose to share with them) deserve to know that your daughters have a sibling. I don’t want to get into the details of everything in case you had no desire to know, but please know that situation is behind me and it is now and open book. Whatever you need to know, I will answer. I wish you all the best.

Edit: attached is a text between him and I when I told him I was pregnant that I might send to her.
