I'm not sure what to do. We've been together 3 years. She's known about a kid I have that I don't want anything to do with. She's now given me an ultimatum to meet the kid or we aren't getting married. I'm at a loss of what do to here. The kids mom triggers me due to SA and physical abuse I got away from. I feel like my feelings aren't being considered because I'm "selfish " because I'm putting my feelings first. I've never met the kid nor do I feel any connection. I don't want to lose my fiancé but I just can't force a relationship with a kid I don't want anything to do with

Edit: kid was a result of SA.
