I am a 27 year old female, my partner is a 34 year old male.

Recently he had this women msging him on facebook, in return she said "your girlfriend is beautiful" and he said "she is I am a vey lucky guy" it was all good with me, she is very stunning herself.

Anyway, this morning he was looking at his profile and seen I pressed like on a male model dressed in police gear, he then said since you pressed like on that, I am going to press like on that girl.

Who is he playing at? The male I pressed is a model whom I don't even know who he is, he knows this girl and she was showing off her stomach. And he said 'so its ok for you to press like on a sexy man and I cant press like on a sexy women?

Basicly mine is fantasy, but his is real she msg him and is friends with his sister. Ge then calls me insecure when I find him to be because he decided to act childish because I pressed on a male model, now is saying that he wants time apart.
