I am also in this club! My FI has three kids - two boys ages 16 & 11 and a girl who is 13. I am only 29 and he is 38, so he also started early. They are all from his ex-wife and believe it or not, we get along great! She called me to wish me a happy birthday and even sent me a "Congrats" text when we got engaged. They recently went on vacation to the Riviera Maya and her and her husband went out of their way to check out our resort and grab pamphlets of things that we should do while we are there. I haven't had any real conflicts with the kids. His daughter and I had alittle bit of an issue but I think it mostly stemmed tot he fact that I was another girl oin her daddy's life, we are awesome now. FI and I don't plan on having any kids of our own, so I am treating these children just like they are my own!
