Dear Nazza~
Welcome here to the Forum, and I'm sorry to hear that your relationship is so hard. It is true in lot of FIFO circumstances the one left at home has to cope with the everyday things on their own. At the same time the one away working is in a very different environment.
It is natural to wonder about the missing partner, if there are any difficulties or temptations, and here you have the added problem that your partner has gone well before you were expecting it.
In any successful partnership both persons not only have to love each other but try to look after the , smooth thier path through life and console them when they are upset.
I'm afraid it is not so much a question of being given tips so you can not despair. Frankly it is your partner's job to see to your welfare. Nobody should leave their partner in a state of despair
To turn things aground and say it is you that is being childish or giving him a hard time is to basically deny his responsibility and think he is entitled to blame you and do what he pleases without objection.. Similarly going away without ensuring you are happy with the timing is thinking only of himself.
Quite the opposite is the case, he should be doing all he can to make you feel better.
You said "It was never my place to tell him to not go". This is so wrong. In a partnership you are equal, and have an equal voice. You most certainly can say not to go, and hopefully then work out something that is satisfactory to both.
I wonder if you have thought what things will be like in the future if he goes where and when he pleases, and blames you for natural reactions. Is this something you truly want to live with all your life?
May I ask if you have anyone to support you. A family member or friend to who you can talk about this with . The do not have to 'fix' anything, just care.
Please feel free to come back and talk some more
