Is it normal i hated the series finale to how i met your mother

The show How I Met Your Mother has been airing for NINE years and yesterday was its series finale. I for one felt betrayed, hurt, and emotionally distressed by the end of the episode. Evidently, this is because the entire ending contradicts the whole series. The entire bulk of last season was leading up to Barney and Robins wedding, which had many bumps on the road. Regardless, Ted finally, or so we thought, let go of Robin. LITERALLY, she began flying in one of the scenes and he let go of her hand and it was very monumental. So we as viewers assumed that Ted FINALLY, after many failed attempts, learned he and Robin are not meant to be. However, that was not the case.
Not only that, despite cold feet and second thoughts Barney and Robin pulled through after 22 episodes to get married. At this point I and many other viewers were convinced that Robin and Barney being each others soul mates was established. Especially after Barney's heart felt speech. However, the married couple decides to have a divorce three years later because Robin travels too much for work. Both were too stubborn to meet in the middle. What probably bothers me the most is not only the divorce itself, but how simple it would have been to save it. Robin basically allowed Barney to make the decision with a question.
The divorce was not even the main issue with the hour long episode, it was the death and replacement of the mother. The title is actually named after her. Yet, the writers revealed they planned for the mother to die of illness and have Ted end up with the mother since day 1.This completely contradicts everything Ted has whined about nauseously since day 1.I am referring to the destiny and soul mate BS. This actually brings up the debatable topic whether or not we have more than one soul mate, but that is a completely different question separate from this post. I understand he decides to go after Robin six years after the mother is dead.However, (and this is just my opinion) six years is nothing, my grandfather for instance died at a young age early into his marriage and my grandmother never even considered ever loving someone again let alone replacing him to this day. And sure she might have been lonely at times but that is the logic she believed in.
Think about what would have happened if the mother hadn't died. Wouldn't have Ted continued his marriage with the mother happily for the rest of his life, as everyone promises to when they get married.
But what bothers me is who urges him to take a chance on Robin, HIS KIDS. I find this cruel and cold because his daughter says something along the lines of (after he finishes the story of how he met the mother) "That's not the story of how you met our mother, that's the story of how you still have the hots for aunt Robin, You only wanted to ask our permission. That's the only reason why you told us all this. "
Overall, Ted's daughter succeeded in ruining the entire season for me in only one line.
If I were in charge of the show, this is how I would have written the series finale. Robin and Barney would continue being a happily married couple and the same scene in the original version when he held his baby daughter would still be included. However, a miracle would have occurred so that Robin (who cannot conceive a child) would have been the mother rather than some random bimbo who is referred to as No.31. As for Lily and Marshall, I wouldn't have changed anything besides actually seeing their children. And for Ted and the mother (who I would have without a doubt not named "Tracy"), would live happily ever after and they would have gotten married immediately rather than waiting for 7 years and 2 children.
I actually sympathized for the mother when she took the group picture. I felt that she was excluded, especially after she died and Robin basically replaced her.
Lastly, Robin and Ted would have never lasted. If they'd made an epilogue of what their relationship would have turned out, logically it would have ended much like the way as it had in the earlier seasons. Except now that they're both old, the issue of rushing into a future (kids and marriage)which they always disagreed on in the earlier seasons wouldn't be a barrier anymore. Also, Robin is presumably retired and no longer traveling.Thus, her job wouldn't ruin her marriage the way it did with Barney. Bottom line is, if Robin and Ted actually made it as a couple by all odds, they would have simply gotten lucky because of the conveniences of where they are in life. They would never really be each others soul mates.
IS IT NORMAL I HATED THE SEASON FINALE? DOES ANYONE AGREE WITH MY LOGIC TO AT LEAST SOME EXTENT?
