Don't worry about being his friend right now. That is your choice and quite frankly, you aren't *there.* I would suggest listening and being cordial or *friendly neighbor.*
Focus on you and your child. That is your primary concern along with protecting yourself financially. Your h as you know him is long gone. Let him do his thing and you do yours.
Good luck:)
