Any person that uses sex to manipulate you like that is already dangerous. Any person that says "I'm inviting you over, but I need this gun for protection from you while we're together," has got some twisted fantasies going on in their head, and you need to stay the heck away from that. This is coming from someone who is very familiar with firearms and believes in the right to bear arms. What she's doing is well outside acceptable. A firearm is a last resort, you don't invite over someone you think you need to keep a firearm trained on if you're actually worried about your safety. Keep your head on a swivel, keep yourself safe!
