It is definitely a bad idea for a mentally ill person to ordain in any setting.
I would recommend concentration exercises/jhana, metta bhavana, or perhaps just placing meditation on hold while mental health issues are worked out.
I don't know of any offhand but it might help to know what tradition he is from.
I wish you the best. I can't imagine how stressful such a situation must be. You seem to be handling it with admirable compassion and equanimity. Please do not, amidst your troubles, forget that your spiritual development is important as well. Too often a mentally ill partner can distract from the proper care and compassion you need to give yourself.
Gain and loss, status and disgrace,
censure and praise, pleasure and pain:
these conditions among human beings are inconstant,
impermanent, subject to change.
Knowing this, the wise person, mindful,
ponders these changing conditions.
Desirable things don’t charm the mind,
undesirable ones bring no resistance.
His welcoming and rebelling are scattered,
gone to their end,
do not exist.
