So I'm curious why you have come to the conclusion about not blending families until after D is 18. Please don't feel obligated to answer, because I'm certainly not questioning your decision, I'm truly just curious. Now, granted, when I got married, I had always been single so my XH had kids, but I didn't. His were 12, 14, and 16 when we got married. Sure, there were some growing pains, but we all adjusted. Obviously, it would be different if you were marrying someone who also had kids and the adjustment would be different, but your D is resilient. If you found a good, solid dude, I would think making that big change wouldn't seem so bad for you or D. Just my 2 cents and not judging you. You have to do what works for you.
Like the post above says, good things happen to those who deserve it and you definitely do. That timing, though, huh? Lol....sometimes you just want to tell people to step on the d@mn gas!
