We are TTC at the moment. Have been together for 8 years, married for 3. I won't go in to how it all came out, but tonight my DH told me that he got an ex gf pregnant when they were together but she miscarried. I just can't believe he hasn't told me this before. I now can't stop thinking about him potentially being a family with someone else. I just feel like when we do eventually get pregnant, it will feel less special somehow, knowing it's not a first for him. I also feel so sad for him that he's had to deal with this for all these years and hasn't told anyone. AIBU to be upset about this?
