I moved back to the UK 18 months ago with my partner after 8 years in Oz, My dad died so I think it made us homesick. since we have been back we have both not settled at all, I think we have changed and are not happy to settle for life in the UK, and we live in a great spot. work is hard everyone is pretty miserable and the weather terrible. We are returning to Oz in September hopefully and I cant wait. I don't see anything wrong with spending time in either country if that's what you want to do, we may go back and then in a few years decide we need another year in UK why not, its your life you only live once and you have to be happy. don't let what other people think make you feel bad for it. I don't regreat the time in UK as we have been able to spend time with family and I have been here to care for my step dad who has terminal cancer this in its self has made us think life is to short not to enjoy. At the end of the day ping ponging is not so bad, only on the finances... but happiness does not come from the wallet..
