Re: feeling unappreciated by GF
My advice would be make her appreciate you. Stop putting so much into the relationship, and in turn she will put more in because she sees you not being as interested. what you have to remember is it's a game, try to find a balance in the situation and make her want you as much as you want her. And after that if she's still dead set on having you put in all the work, kick her to the curb and be adamant about what you want and that it's not working. more than likely she'll be back.
