Help, girlfriend's words hurt, and I don't know what to get her for her birthday...?

Thats tough and two years is not too soon for a promise ring but maybe she feels like she's being tied down to you just explain to her tat it's a symbol of love and willing to wait for here not an engagement ring, the sex well maybe shes one of those Isidore people or just wants to wait till honeymoon but it's a good thing you don't pressure her but maybe you could turn her on constantly yet don't make it seem like you want sex so then she begins to cOme after you
