I can really feel your pain. My last break up left me on a similar side of the fence. I know she will never find anyone who will love her like I did. It took me a long time, but I realized that some of us don't get to spend our lives with the one we love so much. When the other person wants to just be friends..I know just how you feel. I used to identify my self as her other half. Now I must be whole even when it seems impossible. There is love out there waiting for you, dreaming of you.

I am in a similar boat as you. My last boyfriend broke up with me and for a while we didnt talk. Then one night we got together and yeah, that was fun. We kept getting together and hanging out. Then i was wondering why not make a move for it and ask for another shot. I did that and he got mad and said something about how he likes how we are. So i left, and after him talking about how he wants a certain girl that im clearly not, i noticed im way better then that. Which you are to. Its going to be hard to get over him, but it will be a day at a time process, and take as long as you need. Dont ever think your not worth nothing. Because you are worth everything!
Remember that

I just got dumped by my boyfrind of six months I thoughts he really cared abuot me but I guess he didnt I felt so worthless. I wanted to cut myself so bad. Than I stated to like my male friend and now we are dating. I hope you find someone that can make you happy. I know its hard to get over him now but soon it will heal you may not forget him but you may find someone better. Someon that will want to be with you for a long time. I hope you are okay and I know you will find that someone special.
