My ex told me that he loves his girlfriend but, he's also told me some not so good things that went on in their relationship, what does that mean?

all relationship has faults there is no perfect relationship

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.  

i cannot see any of the options
