I just wanted to say you shouldn't feel terrible for him as he's young(I would insert it as a quote but I'm daft at this technical stuff lol)...
You said he's been forced to be a father...I am sure he knew what the possible outcomes of intercourse were (not that I know your situation) .

Don't waste your precious energy feeling terrible for him, you have yourself and your bubs to be concerned about.

For your health and sanity you could start by toddler taming him . Next time he 'has an issue' tell him you'll talk to him when he's calm - and ignore him until such time. Thats what I do with my toddler and she learns quick how to get my "positive attention" (and not the negative attention from tantrums etc).

Good luck!
