Search Results: staying friends with ex

My best friend and I got into a fight recently. About a boy, I'm now dating and I really really like. To start off, I broke up with my ex boyfriend about three months ago and met my boyfriend when I went to my grandma's house for a two weeks and a half. Turns out he goes to my uni but is just in a different department. When we both returned from our vacation, we constantly met up after school, and I din't tell my friends because I was afraid they'd judge me for seeing someone right after my break up so I was waiting for the right moment.

Two weeks ago, my friend tells me she likes someone from her part-time job and everything. I ended up finding out it was my boyfriend. During that time, I stopped talking to my boyfriend and basically broke up with him but staying away from him hurt too much and we ended up getting back together.

Because of this, I decided to tell my friend I was dating him and she didn't react well. She got mad and called me a slut and that I was stealing every man from her because, she used to like my ex boyfriend too but he liked me. Before him, there was another guy in our high school who we both liked but he liked me instead and I decided not to pursue anything with him at that time.

I feel terrible towards her and now she says she doesn't want anything to do with me. Our friends found out and now, half of them are saying I'm at fault but I honestly don't think and I can't break up with my boyfriend because I seriously love him way too much to give him up. Yet I do want to make it up to her.

How can I fix things with her and keep the person I love? Is it really my fault her crushes liked me back? This isn't even a boasting post where I'm trying to look desirable. I never did anything to make them like me.
