H. lividum is not one of the most difficult spiders to get mated,
I have mated a couple of females in the past, I have not lost one male to a hungry or pissed off female
On two distinct occasions i have left the male in the enclosure of the female to live communally for up to 2 months at a time.
During this period they stayed in the same burrow without any aggression from either of the two.
This is not only my female, I have seen a few other females reacting in the same manner.
Ones first mating attempt can be nerve wrecking and terrifying but it will become better with time
I would not be too worried about the male, he'll probably do fine
One piece of advice get him into her enclosure and leave them if you poke and prod at him too much it will put him off
and might spoil your first mating attempt
Let us know how the mating goes
if you have any questions your welcome too send me a PM.
