Discussing your feeling with him isnt selfish. I think you have met a man you like and are in love, which is great. Its been a relatively short time though for him and your relationship. I am not invalidating your feelings or relationship, but 3 mo. is a short time and you really dont know him yet.

I would just share with him that you need to talk and express to him what you did here. IMO at least he will know where your at. As far as the pictures go, I would just let that be. She died 4 mo ago and his child cared for this person. I could understand the pictures. It might make you insecure, but find a way to deal with it.

Your in a difficult spot and I hope you can build this relationship on friendship and trust. Good luck.
