Worthless

"She's lucky to be with him."
I've had this sentence that someone said Saturday night running through my mind.
I think it hurts this much because it reminds me of something the guy I was dating back in the fall (I'll call him B) said on October 30th after the Halloween Party. He said "I wanted to invite you (to a different Halloween party), but my ex was there and we're kind of trying to be friends. It's a little awkward hanging out especially if she brings a guy or I bring a girl."
It hurt. A lot.
So much so that I remember almost exactly the words he said and place that it happened. It was like I wasn't important. I was just some girl. Two months after meeting, I was just some girl. I remember thinking (after the whole thing ended about a week or 2 later), "when did I go from being the girl he had so many things in common with and felt a connection with to just some girl?"
In this situation, who he is isn't important. It's the words and the fact that I was just some girl who could be let go of so easily like something worthless.
So Saturday night the words branded themselves into me just like the words in October.
I'm not worthless and I'm not lower than anybody, but the implication still hurts, and the thing that scares me the most is that my boyfriend could have the same reaction B did if I get scared and start to pull away like I did with B. Right now I'm this great girl in his eyes, but what if I go from that to "just some girl not worth shit?"
Risk of heart break is far greater now than it was with B. Is it worth the risk and potential hurt?
I believe it is.
That's why I'm here.
