Should i be upsit?

Ok here goes, my husband and i divorced after almost 10 years of marriage because of mutual disagreements. After we divorced we dicided to make another go at it well its been about 8 months now we have been back together and he has been "chatting" with other women on the internet. and just just normal conversations, i guess its called cybering. he says its nothing because he is in bed with me every night and he doesnt hide it fromn me. i tell him that it really makes me angry because not only does he tell these girls/women he is single but gets mad at me if i get mad about it and threatens to take every computer out of the house, wich wouldnt bother me but my son needs it for homework. i was browsing through my pics the other day and found naked pics of some woman i guess he had downloaded, ewww i was pisses so i went into archives and found that he not only talks nasty to other women but every page he has looked at was some sort of . what should i do?
