I've been very stupid about this in general. Just a few minutes ago, I tried to call my ex and found out he was over at his girlfriend's house for the millionth time.

I remember when he told me our relationship lasted "a while" (two months). That was a while ago,though. It hurts to know he won't bother to call me, and won't even be at home to answer his damned phone!!He told me he'd still be my friend, but I feel like I'm just another extra, useless accessory in his life.
I was going to call him because I wanted to ask him what to do: I still feel in love with him. It's been over 6 months since the breakup but he was the one person who I gave my all to,only to be a temporary girlfriend. In fact, I think I lasted the least of all his girlfriends. It makes me so angry that I put my all into the relationship just to be dumped and forgotten about. He played me like a fool; to tell me the relationship would last long and to lie about how he'd wait for me.Total BS!
I've become very fed up with relationships recently and can't even stand to watch movies or shows about them. It makes me very depressed or sick with anger.I know I can't have a relationship with him again, but I just keep fooling myself.I'm a shy person; I don't bare my soul as easily as I did with him, and it hurts to do that. I wish I could just forget about him, but my thoughts about him have been haunting me every day for six months.
I no longer know what to do. Every time I think about how I screwed up and made him lose interest in me, I just start to cry. I've stopped looking and feel very much like I won't have another opportunity. It saddens me to think about possibly being alone the rest of my life.
I gave up on all men weeks ago, out of frustration. Now I'm left feeling disappointed and cheated. I don't want to give any more relationships all my energy and leave myself open to be hurt like this again, and at the same time, I can't seem to shake my feelings. I feel like I don't have a purpose anymore.
