Mama Brown widow with eggs - is that the dad oh the left?

Looks like it to me. My question would be: why is he hanging around? If she's laid eggs he fertilised, it must be at least a day or two since they mated, maybe up to a week (I don't know the time from conception to egg-laying for brown widows). My understanding is that male spiders usually gtfo after mating, if they're still alive.
