Life ☹️

Okay so I've posted before about my fiancé and how he's been different and distant from me but I think I've finally been pushed far enough to leave. I just really don't know how, we live together and I get so embarrassed so I know I'm going to hate having to tell my family and friends but it's something I need to do, I don't want to spend my life like this. So any ladies who have left their significant others after years of being together? We've been together for 6 years..
