What should I do? Options

[miss_isabelle]

I've been with my bf for almost 5 years now.. and last year we broke up because he needed some freedom and wanted me to seek elsewhere but I stood by him no matter what and hoped we would get back together again. It lasted for 4 months and we got back. Now he's loving me more than ever. The only thing is i'm having second thoughts.. I feel like I DO need to experience other things/guys.. i'm still young but the main reason is that he is not the same guy I use to date. He changed psychologically because he went through a certain traumatism and now I feel like i'm loving him less and the more I feel that way, the more I feel like breaking up. I feel bad because he's going through a rough time but it is affecting my own life and depressing me too.. I need an uplift more than anything and he can't help me right now!
