Can we say "INSECURE?"

My ex bf(of 2 yrs now)invited me to his graduation party. I went, but only stayed 10 minutes. His mom took a picture of us for his scrapbook. I gave him 2 pictures>A favorite 1 of his from when we were dating, and one of him and i on graduation day. On the picture from the past, i wrote>I miss the days you held me & the days I heard ur voice- i miss the days you were here - Us fallin apart was not my choice- I missed the days you kissed me & the feelings we used to show But most of all i miss the guy I used to know!(but i didnt sign it) on the back of the 2nd picture, i wrote>Promise me…that’s all I want. Just a promise that you will never forget me. Tell me I changed you somehow. Let me know that I had an impact on your life. Promise me that you will always remember me. Losing you was hard enough, but I don’t want to go on knowing I meant absolutely nothing to you.(didnt sign this 1 either)(My ex is moving to chicago)(im really gonna miss him)!!!well anyways> 2 days later i get a text message from his EX (they act like they are still going out)and shes wanting to know whats up with the pictures i gave him, and why i did that! She told me that she cares for p alot, and that he threw the pics away, she he told her told he was gonna show MY bf the pictures.(Thinking or hoping that my bf would break up with me) My ex told me he didnt throw the pictures away, and that hes putting them in his scrapbook (he obviously tells her something different then he tells me) anyway…He told me he just thought it was weird. BUT….it wasnt weird of him to put “gotta call me sometime” Love always P in my yearbook??? i wrote alittle something of no value in his, and just signed my name at the end. So now his ex wants me to call her because she wants to know why i did what i did. Everytime i talk to my ex, or do something, he has to run, and tell HIS ex, and then i receive these stupid little phone calls from her telling me to either “leave him alone”, or “he doesnt like you”, or “wanna to talk to you”!! All i keep thinking is “WHAT AN INSECURE LITTLE B*TCH!!! Give me some good stuff to throw back at her…IF i decide to call her back!! She thinks that im using my bf to get my ex jealous! My ex and i havent been together in 2 years, why the hell would i start using guys now after all that time? DUH!! Besides>my bf is a wonderful guy!!!
