Aqua85, I was thinking about you the other day and wondering how you were going. I am sorry to hear this is happening, it must be very stressful. I second everything pp have said, that telling your friends for support and maybe going back to the uk. You shouldn't be treated like this, and I worry what he will be like with a small Bub in the mix which has the ability to stress even the most happy and supportive relationships.
You mention that you are concerned he is having some kind of breakdown and feel you should help...while I understand what you are saying I think at this time it is more important for you to look after yourself and your baby.
It's great that you are talking to your mum tonight, I'm sure she will be supportive. Wishing you all the best.
