I'm 19 and my partner is 20.we have been together for 4 years.i lost my virginity to him and our sex life was good for the first 2-3 years. since then we barly ever have sex if we do its because i ask/initiate it. im starting to get really concerned about our relationship as it is becoming more of a friendship rather than a relation ship... he brought me an engagemtn ring over a year ago and still i have not been given it.im worried that i am not good enough for him but i dont see how this is possible as i have lost weight and am looking better than ever. whenever i bring up the subject of sex he basically changes the subject and says that he is tired but work wise nothing has changed in his shedule. along with this problem he also tells me lies or hides things from me like nothing huge but just stupid things..i often think that if he is telling these little white lies is he capable of doing more?????
