Dear, Regijones..
Don’t move to NZ.
From what I read, it seems like he is indeed is unstable at the moment. I am sorry you have to hear this, but the truth is, you are a burden to him right now. If he’s in bad depression, being loved so hard while knowing you can’t be a good partner, is a burden. The bigger your love for him, the worse you made him feel about himself.
Set him free. Give him some time. Let him learn again to love himself, stop texting him, find any distraction like new hobbies or activities. Don’t feel like he puts you on standby, don’t, it’ll also makes him feel bad. If you really love him, just move on with your life and be happy instead.
Love is the most complex thing in this universe, but it is also the most simple thing. Have faith, stop forcing things. Sometimes you just have to give in and let things happen. If it’s meant to be, it will be.
Dee.
