I (f22) have been dating my bf (m26) since shortly after winter break. The relationship itself was good and I enjoyed it. The one recurring issue I had was his best friend (f18).

We live in a small town by the Canadian border and this girl has no car. She can easily walk to work or school since our town is literally only 1.3 miles long but my boyfriend drives her to and from work and school everyday. It bugged me a little bit since it cut into what we were doing but I tried to not let it but me since they were doing that since before we were together and it gets to -40 in our town in the winter.

However, this girl has also been inappropriate with both me and my bf in the past. Leaving me a "funny" little note in my bfs car about how she was here first, trying to sit on his lap during a party, etc. He also let it slip that she hated me which upset me greatly. We have had points of contention but I don't hate her. She's in a committed relationship and I don't suspect her of being attracted to my bf because of her personality but she is very immature.

The fact that my boyfriend was attached to the hip to an 18 year old girl made me uncomfortable sometimes as well. My bf has major chronic depression and his bff is emotionally unstable and openly mentally ill so I get that they connect but it also makes me uncomfortable that he does it with a young mentally ill girl with poor boundaries, especially since I was addicted to drugs and homeless as a teenager and she reminds me of myself at that age.

We agreed to go on a break for two days while I thought about the relationship and he was supposed to take a break from her too because he admitted that they were codependent and he wanted space from her. The understanding was that if I didn't talk to him within two days we were over. But he showed up to class with her yesterday and sat next to her like always. I gave him a bag with the gifts he had given me today since it's day 3 and he sent a text asking why I gave it back but I haven't responded. I don't think he really expected me to leave him.

I care about him and I enjoy our time together. I don't want him to not hang out with her at all but being her chauffer and hanging out with her everyday, multiple times a day was grating. I felt extremely hurt when he didn't even PRETEND to take our break seriously and not sit next to her in class. It would be different if he just drove her and at least tried to send me a text saying that he wasn't hanging out with her outside of class but he didn't.
