About 4 years ago I was seeing a guy......he was engaged. Really stupid mistake on my part and one that I have regretted since. When I found out his gf was pregnant I ended it and we didn't see one another again.
I have just started dating a guy who I really like but I have just found out his step sister is the guys wife I was sleeping with.
I feel awful. I thought it was all behind me. I know what I did was wrong but I was in a really bad place at the time.
I don't know if I should just end it with him now or try and see how things go and say nothing...
