No he hasn't threatened to take him and yes I would use a contact centre but he has refused to do this
Only in the way of his unstable text messages threatening suicide, stating he won't be here for long and alot more along those lines. I have offered him to see his son with my mother for first few times at least so he can familiarise himself with baby's routines etc and become re-introduced to him as been told by health visitor that at this age they form very strong attachments to those people he knows.

In that case your offer of a Contact Centre is a reasonable one and one you should make in writing.
Since there has been recent Domestic Violence you should be able to benefit from Legal Aid so you shoudl find a local solicitor to assist you
You can find one on this website
I hope that this is of assistance - please ask if you need further details
