Relationship issues .. Extremely hurt PLEASE READ .

I'm 17 & I was with my ex for 2 months & we were best friends for 2 years .. I told this guy everything , including all about the good for nothing guys who played with my heart . He was the first one I called about everything . My last ex hurt me the worst & I was still recovering 6 months later . I started getting serious with this one guy until my best friend told me his true feelings for me . I dropped that guy & basically everything & "talked" for about a month with my bestfriend before we made it official . And in that 2 months , he tried breaking it off with me 3 times . I blamed it on him being bipolar which is really diagnosed & he's apologized for trying to break up with me the two other times , but now we're broken up as of now since Sat , Jan . 17 . His excuse at first was that he wasn't ready to be with me because he was still fucked up from his ex hurting him . Then his second excuse was that he never really wanted to be with me , he just wanted to be close again since we had fallen off because of me being with my other ex . I'm beyond hurt . He used to send me messages like this ALL the time .. Made me think that he was telling the truth . He knew what I went through . So why would he lie about his feelings for me ? He did some stuff to me without asking for anything in return & we never had sex . So I don't understand the purpose of him meeting my parents , telling me how much I mean to him , buying me all these gifts and pulling me out of my relationship to be with him if he never wanted me that way .. I can't get over him . How long should I wait before trying talking to him again ? Or should I not at all ?
