Hi Tilly. Despite the late call, it's good he has found his voice on the subject. And, if these types of conversations don't come easy it means the more.
However, at some level knowing him as well as you do you already knew how he felt - he wants you to stay but he really doesn't want to go. So I suppose you now have to work on what is going to change/be different such that you can continue to spend your lives together. My advice would be go and have your holiday but make up your mind to return to your husband and pets before you go. Use the break for some thinking time, to refresh your mind and spirit, catch up with loved ones. Look at it fresh when you return. This is such a huge decision, to rush into it would be a mistake. Flying back and forth is not cheap. But if your husband is earning well and you are working, the extra money spent is worth it and pales into insignificance when you look at the financial cost of divorce - which this may end up becoming if you continue on this path. Not to mention the emotional cost. How will you feel if after you separate your husband takes up with another.
My best wishes to you. I know how it feels to have the heartache that pulls you 'home'. And I put home in commas because, for many of us though not all, once we become migrants home is in two places. It is the hidden cost of migration that we can't fully realise until it becomes part of our very being.
