So long story short when I met my husband he had kids from a previous relationship the kids were babies ( twins) they were 1 years old at the time the mother was well, never really a mother to them me and my husband got married pretty fast and the kids were really attached to me well the bio mom kinda just slowly disappeared out of theirs lives by the time they were 2 so I ended up adopting them ..well we really never told them about her because we didn't want them to feel like they weren't wanted or love now they are older and can understand more about to be 13 I want to tell them about their bio mom (btw we live in the same small town as her and she never made a effort to see them) I'm just so scared because I don't want the to feel like im not their mom or anything pain but I know they will be hurt and I just don't even know how to start anyone out there been in this situation before or have any advice
