Help me i need advice to save my relationship?

my g/f and i have not been on good terms latly at all. we have only been together about 2 months but before that we were together for nearly a year. we broke up for about 4 months and things were total hell between us. we hated eachother and nothing seemed to make it better until i got a new g/f and she ammediatly wanted me back. so we ended up back together but things are misserable. we both want this relationship to work out but i have no idea how to make things work. can anyone think of a way that could make things better? i dont know what to do i want to be able to talk to her today and make things better but she is so moody and that is one of our biggest problems. also she doesnt like that i smoke which brings problems. she thinks that sex just gives us so many problems and that if we do it less things will get better. i dont understand that at all and no matter what that doesnt change but if someone can agree with her and tell me how i can stop that. just any advice please.Help me i need advice to save my relationship?
dude! she sounds very controlling. Do you want that? There are millions of girls in this world. Dont settle for a moody non sex wanting telling you how to live type of girl. geeeezeHelp me i need advice to save my relationship?
I'm sorry to hear you are going through a difficult time in your relationship. About the sex part, i say she is right, the fact is that if you are not mentally connected, you cant be physically. Sex must be done whilst being in harmony with each other, or else it could lead to things going worse. Girls are more sensitive when it comes to sex, and for us its important to be in good terms with whom we are with, to enjoy sex. So my advice is try to work thing out on the emotional part, don't focus much on the sex life for now. Maybe try to take her somewhere she wouldn't expect and surprise her, just talk and open up to one another, compromise about what you dont like in each other.
