Girl is dating me and another guy
And as for dinner tonight, that was incredibly manipulative. Whether you really like her or not, you have to have some integrity and realize that she treated you poorly before and is continuing to do so. If you take her back under these conditions, you are in essence giving her the green light to continue. She's like a used car salesman that's trying to sell you a lemon by suggesting teh take back.
Dating may also involve two or more people who have already decided that they share romantic or sexual feelings toward each other.
The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time.
While the term has several meanings, the most frequent usage refers to two people exploring whether they are romantically or sexually compatible by participating in dates with the other.
Women eventually won the right to vote in many countries and own property and receive equal treatment by the law, and these changes had profound impacts on the relationships between men and women. In many societies, individuals could decide—on their own—whether they should marry, whom they should marry, and when they should marry.
A few centuries ago, dating was sometimes described as a "courtship ritual where young women entertained gentleman callers, usually in the home, under the watchful eye of a chaperone," but increasingly, in many Western countries, it became a self-initiated activity with two young people going out as a couple in public together.
Whatever made her lose her attraction to you will still be there, if you know what it is, dont take her back. If she had sincerely felt like she had made a mistake (which she doesn't, trust me) she would have thought it through before contacting you. A hard smack of reality upside the head would be good for her.
