This is really helpful! I am almost exactly the same as you. First love, working on my dissertation. Both me and my boyfriend are sensitive people. Recently before the period i have been super emotionally vulnerable. Usually what i do is I hide myself away from him during this period. But he said he wants to see me. And then i get emotional by things easily and he just shuts down and say he cannot deal with me crying. It hurts me so deeply that i feel he has abandoned me. I was definitely not doing it all the time though. But clearly he is stressed out by the past times when that happened. So i have been pretending to be very positive and happy texting him for the past few days. But in fact i am still feeling extremely hurt and i still don't know how to get over it. When we started dating, it actually took a long time for me to open up my emotions to him. He told me that i can talk to him about anything. But my emotions often come with crying. And i have explained that i cannot control crying when talking about emotions. The only way to avoid it is to not talk about it. I mean, i can deal with my emotions. I just need to be alone during that period. Now that i know he cannot deal with it, how much should i share with him in the future? If he only accepts the positive and happy side of me, is this relationship a one that i want? I don't know... Now my only strategy is just trying to pretend to be positive. Sometimes by pretending, I really feel better. So it is working at the moment...
