17 year old sister having relationship issues, this combined with my friends’ issues has made me more wary of relationships for like the first time?

So my sister is 17 and a junior and her boyfriend is 15 and a sophomore, I’m 18 and I just finished up my freshman year of college.

So my sister has had lots of drama relating to an ex best friend. This girl harassed my sister online on Instagram, and on there she told her to off herself, called her a certain c word, and threatened violence against her. The stupid brat is also a close friend of mine’s ex and she has told him to off himself through sockpuppet Instagram accounts, so yeah it was bad. My sister’s boyfriend was very good about the initial situation, despite his age.

However, this girl has two friends who my sister has to interact with daily who treat her awfully, and my sister’s boyfriend is “friends” with them (they make fun of him a lot according to my sister). So despite my sister’s pleas, he often ignores her to go talk to them during class.

So last week at school she talked to him about it, and he didn’t listen, so my sister left school early on Thursday, and she had a concert that night where he didn’t comfort her at all, instead, we watched him goof off with his friends from the crowd, which told my parents and I that she needs to kick him to the curb. So on Friday, my sister didn’t go to school again, and at the end of the day, they broke up, but then she wanted to talk to him, and they made up over FaceTime so she’s fine now but the can has been kicked down the road.

The last day is June 22 and I’m almost certain that they’ll be done for good by then. I just hate watching her get hurt, but this time, she made her bed she has to sleep in it.

Upon watching this, and some of my friends’ relationship woes back in college, I’m wary of relationships for now. I feel like I have to work on myself and I’m not up to getting my heart broken. The last time I had a girlfriend was in the fifth grade, and even at the age of 10 she broke my heart way back in March 2014, and even now, all these years later I don’t wanna do that again lol.

I ran out of space but I want to clarify that yes, I’m over my middle school relationship because obviously, it’s more that I remember that feeling and I just don’t need that right now, plus having nobody to answer to but me is kinda nice ngl
