hi lonely, u have expressed ur pain very beautifully.the pains u r experiencing now and the way u have expressed is so lively.it just shows how much u r suffering at the moment."I know you don’t complain anything to me. It is because you don’t even care" how true! only people who get enough dont complain or who don care.who want to be together n be happy n who want to make the other one happy do complain coz if he himself is not happy cant make other happy.for the happiness of other he should try to keep himself happy or at least needs encouragement to do something for the other one.very phylosophical.pains n sufferings give birth to thinkers n philosophers. "I keep telling you what I need. But you never give me that". this shows he does not love u at all.if he cares, he would have at least tried to give what u want.he would have listened to u.he does not care about ur happiness.he does not get happy when u r happy so it does not matter whether u got what u want or not.n of course people get changed when they feel neglected. "don’t know what is wrong with me. I am so depressed. I just feel like crying all the time.Why am I like this?I know u think its one of my drama. You think I am just looking for reasons to give you hard time. God!! I don’t know .. I know I wasn’t like this.. I was strong. I knew what I was doing with my life. I am so confused now. I am so lost. I am completely a different person now. I am not happy the way we are. I am not happy at all..I am not sure where we are going?? I feel like I am stuck. I feel like there is no way out.. I am dying inside.." this is what happens when the person u love does not give u what u want or at least does not care about u.if he can not do its a different story but not caring n not willing to do even if he can then its just to behave u as a granted. hi lonely my honest suggestion is: just kick that person out of ur life.its hard to break up or simply go out of someone's life u love but he does not deserve u.had he not had affair with anyone, i would suggest u to solve the problem by discussing in a mutual way.u try to make him happy n he will try to fulfill what u want but he has betrayed u, he does not care what u want ,he does not want to listen to u how u feel.if he is changed coz of another girl, then u just go out of his life coz he is taking u as a granted and behaving like this.one should not b too weak coz nothing is granted here.we need to work hard even to get one's love.if u don get anything from him, what is the use of being with him? just keep on complaining does not help.it will create hatred for u even more coz one who does not try to make u happy wont understand ur pain of needs as well.u can even live alone freely without any responsibilities.such guys n girls need to be punished who just don respect the sacrifices of others who love them.nothing is granted here, nothing!everything has its price! astu:
