I've been in a relationship with my girlfriend for a year now, but in the past 3 months there's been a bit of a problem. It's connected with the issue of respect. For those past 3 months my gf would, from time to time, start annoying me for the fun of it, with "jokes" like "That guy is hot", "I went with a guy to the swimming pool". I find these "jokes" absolutely sick and insulting. She always says 30 seconds later it's just a joke because she likes when I'm jealous. Well, I don't. I effing hate it. And I'm getting really uncomfortable with it. How should I confront her about it ? I suppose I should wait till she does it next time, but how should I go about it ? I do have the ability to be a bit tougher than natural if she displays bad behaviour, but I don't want to overdo it, if you know I mean. Walking out of the room isn't really a solution, because she'd say I'm going mental or something. I think I should say something. Something that isn't that nice to hear to make her stop. Any suggestions ? I really want this to stop because it kills positive thoughts about the relationship.
