would you let them sleep together under your roof ?
They have been together more than a year, and seem to have a good relatoonship. I know they sleep together elsewhere and have discussed contraception openly with them both. I personally think its ok; DS' father thinsk i ma being irresponsible - There are two younger DS at home - DS1 and GF sleep in the sumer house if she says over, Its not more than once a week really
