Why am I such a doormat when it comes to apologies?

[Tinkerbell cat]

I don’t think it’s her aim per se…but I think she would have a sly little chuckle to herself if we did. Since yesterday’s vent to you guys my boyfriend has messaged her asking her to end this feud and he has apologised for any offence he may have caused. I’m annoyed she’s got her way but the support from my bf means a lot. However, she has since screenshot his apology and sent it to all of our mutual friends mocking it.… she really is just absolutely vile and I’m officially done

Is there something wrong with her? Who gets on like that. Just strange behaviour. Get some distance and space between the two of you, it will help you so much and you will be ten times stronger out of that and away from that toxic behaviour. I know it isn't nice because its your sister but you need to put yourself first here and she's way out of line. xx
