So I have been dating a guy for like three years and he is basically my high school sweetheart. Like every relationship we have had our ups and downs. I feel like our relationship consisted of more problems then happy aparts. After three years I kind of just feel like letting go and being free. Although I love my parter very much I don’t want to go because I don’t want to hurt him. We live together and I feel like all we have done is more fighting. I don’t know what it is or how to make everything better. I don’t know why I feel like this...sometimes I just feel like flirting with other men. Why do I find myself having sex with him, but wanting it from other men?
