I think the advice about counseling is spot on.
The only thing I have to add is my experience. Take it FWIW (probably about 2 cents).
Between my DH and I we have 4 boys:
His- 33 and 30
Mine - 18
And ours - 13
The 33 & 30 yr old barely acknowledge that the 18 yr old even exists. It's been this way forever. I've asked DH about it over the years but there's never really been an answer.
They only slightly more acknowledge the 13 yr old. Again, I've asked why but there's never been a real answer.
Maybe it's the age difference, maybe it's being step-brothers and half-brothers, maybe it's resentment over their dad starting a new family, I really don't know. But it is something to think about, the blending of the two families. (If you go the marriage and children route.)
Then there are grandchildren. The 33 yr old is not ready for children but the 30 yr old has 4. I understand grandparents spoil grandchildren but DH has allowed the grandchildren to do things that the 18 & 13 yr old were, and still are, not allowed to do. They know that they were, and still are, not allowed to do those things and they have called him out on it. DH laughs it off. It is causing some very hard feelings from the 18 & 13 toward the 4 grandchildren.
I don't see a time when the 18 & 13 yr old will ever be close to the 33 & 30 yr old or the grandchildren. And really, that's sad.
I am in no way implying that you or your future children would be this way, please don't take it that way. I just want to say, and give a real life example, of some things to consider to help you be better prepared for a blended family than we were. (If you go the marriage and children route.) Best of luck to you!
