How bad is the I-95 thing right now?

Did i do the right thing here? Very long but i do need advice please :/?

• I know its long but please i need to know is she using me or confused? And did i do the right thing by ending itt :/ Keep in mind she has told me she just wants to be friends, but than she goes and flirts with me and says sexual stuff so its confusing shes even sent me 2 ' sexy pics' after she told me she has no feelinga for me so you can see why im confused. I confronted her about her feelings for me saying is it just some fantasy of mine that we will end up together? She replied with "...." but after that i told her im serious and really have these thoughts she than said "i think you should stop having those thoughts :/ i mean idk ah" i told her i just dont want to be stringed along anymore and if she ever has these thoughts'.. were both teens so i wonder if shes confused.. She replied with a text she saved from me i sent her like a month ago, it basically said "i dont see our relationship going anywhere and i dont see the point" i was really angry because i found out she hada bf :/ but i feel like by sending that she just wants to make me feel guilty, so i told her regardless i still care about her blah blah and she never replied to it.. than i told her its okay we dont have to talk about it and she said okay and changed the subject >:( wtf is her problem why cant she just tell me how she feels.. we use to have a thing but since its long distance she didnt want to commit, some people say she is using me as a backup and what not but i feel like theres more to it than that.. we went on a cruise she let me get close some, but shed generally back off but that is because she has a bf. I did rest on her arm one night and we got real close several times im sure if her bf saw hed be mad.. thing is she wrote her bfs name in the sand and took a pic of it right in front of me, which upset me greatly than she chose to go to her city instead of coming back to mine after the cruise to see some other guy who was visiting (although this is our last time seeing each other in possibly forever) but she did take her shorts off right in front of me and slept in her underwear, but we were on different beds but still.. when she did this she said "Whoops didnt mean to do that in front of you" ahh what to do..? also when we first started talking(about 2 years ago) shed actually tell me she liked me more than her bfs and if i was there shed date me, but now she will never tell me how she feels.. i sent her a gift in the mail she will mos loved with the note on it says i miss you and love you and she got it last week. But our relationship means so much to me, she introduced me to my favorite tv show of all time, so many songs remind me of her, it sucks bcuz back in feb when her old bf broke up with her she started liking me again for like a month.. she got my gift the other day and she liked it of course ha, she told me she loved it.. Sigh Shes my first love, i dont see why shed be in a 2 year relstionship with me if she didnt care; she means the world to me i dont want to let her go but i finally sent her an email saying goodbye and telling her how i feel.. I also told her not to reply back but now im so lost did i do the right thing? :( Okay she texted me with a " :D!" a few minutes ago so im guessing she hasnt read the email lol mmy heart wants me to reply so bad ahhh should i just ignore or whut..

• Answer:

  Okay 1) Shes playing you. Two years. Shes either using you as a back up or playing with you. I mean opps i accidently got nude in front of you. Oppsi. Yah. NO. Then writing her boyfriends name in the sand?! seriously? 2) your too clingy. If you keep following her like a puppy dog, she likes the attentions. Shes playing ytou IDIOT GIRL LET GO OF HEr
