For around 6 months my child’s father was still sleeping with me whilst he had been in a new relationship with his girlfriend. I had no idea about this for those 6 months - I found out on social media last year. I was distraught. I did not tell her though, nor did he. We stopped sleeping together, he continues to be in a relationship with the girlfriend. I feel like what he did was very disrespectful to her - and me, as I wouldn’t have slept with him had I known he had been with this new girlfriend. Girlfriend now plays an active role in child’s life when child is with him however he refuses to let me meet her. I still feel wronged, and I feel like she has been wronged too. Just wondering what anyone else feels about this situation? Child’s dad says this woman is love of his life and I believe that, however I wonder if he’d still be sleeping with me if I’d not found out about her? We didn’t speak for a long time after I found out, he told her that I was upset simply because he had a new partner, but that wasn’t the case, it was the fact that he kept her existence from me while he was still sleeping with me. How would others feel if they were in the girlfriend’s position?
