Am i jjealous or sensitive or just feeling normal about this?

my mate and me had wanted a boyfriend for a while, she then went out with this skank of a guy last year who stole from her and didnt treat her well, i helped her throgh it and a month later she had with a guy i hated, and another month later she went out with a guy and dumped him and now shes got another guy possibly on the go and she says she really wants a boyfriend. iv talked to her before about how i felt and she said she would help me find someone, but shes only looked for herself. any thoughts?
