I am very sorry to hear about your wife, losing a spouse is the hardest thing someone has to suffer, and I for one would be a wreck if I ever lost my spouse.
I am glad to hear that your daughter said that you and your late wife are her parent's, that is the most... Loving, and caring thing a child could ever say to an adopted parent. My cousin was adopted, and her parent's are... Not the most loving and caring, and that is what got me worried. She is upset because she never got to meet her real mother (Who passed away from drugs).
I do think the trip idea was an amazing idea to do for her, and in remembrance of your late wife, it is quite honorable. I do thank you for sharing your story with everyone here, including myself, it was quite touching.
Oh Eleanor trust me, we are not going to adopt any time soon. But the sad thing about marriage, (Which her and I see eye to eye on) Is the statistic's of the divorce rate, 1:2 marriages end in a divorce... Seeing that rate that high, scare's us because we both said "What if we are dating, and decide to get married at 30 or 40, and we get divorced?" We have had talks about quite a bit of things, especially marriage, because we are both 23, and we both are "future planner's" and we have talked about our past relationships (With both of us being engaged at one point, and such). We are both afraid that what happened can/will happen again, but we trust each other enough, and we care about each other enough to know it won't.
So I would say, once we get married, we will spend two or
three years just with each other, then go out and adopt, if we feel ready then.
