Search Results: pain on my left side

I met this girl a while ago on social media and I've began to love her and I didn't realize she liked me at first but recently she's gotten a new boyfriend and I can already tell it's a bad relationship. One he's overzealous/jealous of her and doesn't trust her at all, two he argues with her a lot, and three he's caused her (not intentionally) to attempt suicide and cut herself both of which she promised me she wouldn't do.

I've tried to tell her to leave him but she won't and it's clear she won't be anytime soon and quite frankly I don't even want to be friends with her anymore as I don't want to deal with the pain that will come if she kills herself or cuts again over this guy. She says she loves me too but It's hard to believe as she never tells me when she's sad or rarely even tells me these things.

Also as I side note I promised her numerous times I would never leave her (she told me if I left she would be heartbroken but it doesn't seem l
