Personally I don't particularly have a problem with Scotland leaving the UK if that is what they want. Last time they voted 55-45 to stay, but that could easily change over time. Equally if NI eventually vote to create a united Ireland at some point in the future I have no problem with that. Wales seems very unlikely to vote for independence any time soon IMHO as it has a much larger English population and also is tied in much closer with England both geographically and economically than NI or Scotland. Country borders can change over time, I am sure we can all deal with it.
