I feel very offended...rant?

[our battles]

So i befriended this girl in one of my classes and i mean shes really nice but she seems to always bring up religion comments. I mean I am Jewish and she is Christian and she has said to me before that she hopes to spend time with her real Christian friends when she was getting a surgery done and there was this girl who hated me cause a guy she liked liked me and they have become friends and when I brought it up because of curiosity she said they clicked because she is also Christian. She has also brought up religion before and I mean I am not like best friends with this girl like we arent super close but do I have the right to be offended? I mean I find it very rude I never talk about my religion and its not like I dont know Christianity I mean it is very similar to Judaism but I mean am I over reacting? I just find her 'ways' or words to be extremely narrow-minded and arrogant. It really makes me mad because I mean its thoughts like those that isolate groups of people by religion. I mean we go to a nonreligious based school and I have other friends who are religious christians and are musliam who dont seem to have a problem but I mean if she did why would she even like befriend me?
Also she sometimes imitates me...do you think i should just say good riddance to this friendship? I mean we are going to be in on of the same classes next year so should i just slowly retreat cause i mean i dont want to have a bad relationship where we hate eachother i mean i consider myself i nice person. some of my friends know her and make fun of her but i always stand up for her like they call her i dunno like a party pooper haha not in those words but you get the gist lol but i dont know...
opinions?
