This guy I like who also likes me is engaged he told me to wait for him should I?

Hell no , you don't love the guy and he loved someone enough to get engaged to them you are just a side from his main course he will always go back to that girl he is engaged to. Just think in your future and he proposes to you and you guys are engaged u will always wonder if he is talking to someone else . You are worth so much more than someone seconds and that is what you will be if you wait around this guy. Live your life don't be tied down to someone who is already tied down .
