Cries i hear at night

All this tears i hear at night makes my heart feel sorrow and slowly sadder and sadder cause i kept thinking of him. I hear my friend cries every night. Some of them cries over the mistakes they makes with their lover and some of them cries thinking of their ex's. Like me, i'm always thinking if am i having a good relationship. Am i good in relationships? am i too serious? am i a good girlfriend to him when sometime's i dint even text him or saying hye to him? Sometime's i told him that i'm ok when i'm really not. I dont want to make him worried or anything. I dont wanna be the type of girl who is very demanding. I always keep secret from him so that he wont geet worried of me. i want everything to be ok betweenn us. And know, i havent heard from hiiim almost 4 days. i remembered the last time i text him. i ask him why he dint reply my messages or call or say hye. I even ask him if i did something wrong. In the end after a few hours he replies. HE said that he was sorry that he dint reply my messages coz he has a big big problem and he would tell me later.and know he said he need's time to think. I was ok with it. I kept on saying ok when i'm actually not ok with it. i kept on taking care of peoples feeling, but they care bout mine? Do they know how i feel. Maybe because i love him so much that i din't think bout me.myself. i dunno when am i going to come out of this shadow of myself. Sometimes i am sad. but most of the time i dint show them.i kept it to myself. Sometime this sorrow that i feel i cant tell anyone. Maybe in front you would see me smiling but inside i'm actually dying and trying to grab hold of myself. thats me.
