Guys there's sth concerning me and i know it's a little bit weird to ask this, but i really don't know what to do.

A couple of hours ago my LTR posted on fb a photo in which she can be seen only from one side, her face not ( looking somewhere, that kind of 'artistic' photos). She has a bra with a little bit of push up, her breasts looking bigger through her blouse.

I started teasing her through text with sth like "so you're showing to the people you have big breasts.. go on my girl" then she told me that i know she isn't that type of girl and i continued joking telling her "so you posted this for the smile you have, look your diples could be seen" (i was being sarcastic cause like i said, her face couldn't be seen in this photo, only from.the side).

Then she got upset and she told me she isn't in the mood for these kind of jokes and that she told me so many times to don't laugh of her, to make this kind of jokes with other girls and better we talk later. I said 'ok' then i went to football and she still didn't text, now she's sleeping cause it's late here but still no message and she probably expects me to do it first even if i wasn't the one who ended the conversation.

As the day passed and it's 9 mars it's the day we "celebrate" 7 months of being together.

Now i don't know guys, should i text her to say goodnight or sth related to our 7 months? If not, what should i do?
