My Ultimate Goal

My ultimate goal is having my own happy family, and living with them happily ever after. It will all be all futile without happiness in my family, even if I made a fortune or achieved a big fame. It's been years since my parents started falling apart. They still don't get along well now. I don't remember when the last time was we went on a family trip was, which is why I was surprised when my mom told me about going on a family trip several days ago. I just can't imagine that. Anyway, I'm glad that my girlfriend has the same values as me on that issue, but even she sometimes says that I'm too obsessed with having to have a happy family and raise my future children well.

There's not too much to correct. A few errors in word placement, an unneccesary 'a', and tenses that didn't match.

'live' -> 'living': this is so that the tense of living agress with the tense of 'having' in the first part of the sentence.

'be all' -> 'all be' to sound more natural. I'm not sure this sentence contains the best choice of words, but have no great correction for it.

'was' moved. The structure should be 'when something was'
