What about my roommate's very frequent flirting and teasing me about my size and other aspects of my life?
Hey, buddy, hi!
You say your roommate is always teasing you. How often does "often" mean? Is it several times a day, or several times a month? We need to have a frame of reference. Sometimes it's just that we think the other person is talking too much, and because we haven't experienced this kind of joke before, we can't take it, so we feel that our roommate is always targeting you.
Also, has the roommate always been like this, or did it start suddenly? If your roommate has always been like this, then you have to see if he is like this with others, maybe this is his customary way of getting along with people, if you can't stand it, you can take the initiative to communicate or choose to ignore it; if it's a sudden change, then is there any friction between you two? Or you are better than your roommate, he is a little jealous, want to flirt to pressure you? It is also possible that the roommate wants to use this way to bring the relationship closer, but the way of expression is not right; or even possible that the roommate likes the person who has a crush on you, he is not balanced in his heart, and he wants to find self-confidence from you. You can ask your roommate directly why he is like this, and if you are too embarrassed to talk, ask around through his friends or well-informed people. Really don't like, it is appropriate to keep the distance, roommates do not have to become good friends, but the surface relationship to maintain a good, to avoid conflicts, after all, every day to meet, stalemate everyone is embarrassed. If you touch the bottom line, you can properly counterattack, with language dislike back, but do not do it, first hand loss, if necessary, tell the teacher, parents or friends, do not carry a person hard. It is best to solve the problem peacefully, maintain self-confidence, everyone is unique, different standards of aesthetics, don't be framed by other people's comments, a healthy and confident mind is the most beautiful.
I hope these suggestions will help you. Good luck!
