Note that it won’t take you very long when being around both twins to know who is who and to be able to tell them apart easily.
Instead of feeling like you need to be around the second twin all of the time, organize specific events to go on a double date, or create group get-togethers. You might like to ask one of your friends to spend time with the other twin. He or she might even start dating one of them! And when you’re alone with the two of them, interrupt their physical closeness by putting yourself in between them.
Remember to treat your twin date the same as a single birth person. What would be challenging, hurtful, or inappropriate in that situation remains the same for dating a twin.
One response to trickery might be: Secretly brand your beau with a mark without him or her knowing. Kiss his or her cheek while wearing that red lipstick, for example, put a small sticky dot on her top, or even give him/her a hickey. Then if he or she comes back without the mark, you’ll know he’s Tweedle-dum not Tweedle-dee and you can call an end to the pranking. Or simply voice your dislike of any such pranking.
As with any dating, check your own emotions and feelings about being with your twin date as a person in his or her own right. Consider how many people of single birth have a problem with clearly defining who they are in life. If you wouldn’t normally date a person who has issues with self boundaries, then your twin date’s closeness with his or her twin will probably become a cause of concern for you. If you find one twin is very protective of the other twin, even when you are around, and tells you to “take care of my baby sister well, or else”, or “treat my brother properly”, this could be a warning signal that the protectiveness will spoil your relationship. Talk to your twin date about it and decide how you feel after hearing the answers. Constantly fighting over the presence of a twin in your dating life is a warning sign. If your twin tells you that their twin will always come first in their life, this signals that the twin hasn’t managed to separate his or her needs and future journey from his or her twin. It might require more time, or you might consider moving on.
