Input: Hi, Reddit. Sorry for the long post, but I want to provide clear details. TL;DR at the bottom.

I'm a sophomore in college. In my freshman year, I made very close friends with the girls that lived on my hall. There were 5 of us in the group total, and we all live on the same hall in our sophomore year. Out of us five, three of them smoke weed occasionally. I had never smoked but didn't have an issue with the fact that they did. When they would smoke, at first they would ask if I wanted to join, and since I said no every time they stopped asking. Near the end of our freshman year I started mentioning to them that I would probably do it at some point, but never really pursued the interest.

I met my current boyfriend at the beginning of my second semester of my freshman year. We're currently in a LDR (\~ 3 hours) and every month or so he visits me for a weekend (For reasons, it's easier for him to come to me than the other way around, and that's never been an issue in our relationship). He also smokes occasionally, but has always been aware that I did not. He's never pressured me to, and I'd told him the same thing that I'd told my friends: I'd probably try it at some point.

During this past October of my sophomore year, that opportunity arose. My boyfriend has a THC pen that he brought with him during a weekend trip "just in case", as he always did (previously, it had always just gone unused while he visited). We had been under the impression that all of the group was going out to a party, but it was cold and rainy, so we weren't sure what everyone's plans were anymore. We went down the hall to ask after hanging out by ourselves for a while. (The four other friends share a suite and are roommates with each other). The first door didn't answer, so we knocked on the other. My friend, Sarah, answered. She said that her roommate had gone out with a friend from high school, and the other two girls had also left to hang out with some other friends across campus. Sarah herself was doing schoolwork at her desk. BF and I stayed and chatted with Sarah for about 15 minutes, where Sarah was still focused on her work and BF and I were awkwardly standing by her desk. After a while I excused us so she could get back to what she was doing. After we realized that everyone else was out/busy, my BF asked if I wanted to try the pen. I said yes.

I told my friends about getting high for the first time over dinner a few days after it happened, and Sarah got angry. I think they were always under the assumption that when I smoked for the first time it would be with them (my friends), since they were really the only people that I'm around often that I know that smoke. I realized this when my friend Michelle joked "\[BF's name\] already took your regular virginity, we were supposed to have your weed one". Sarah was also angry that we didn't invite her to smoke with us. I told her that we did it on our own because everyone else was out and she was busy, and she only replied that "she would've stopped what she was doing if I had just told her". She also said things like "I have no trust in you anymore", "we're starting from square one", and other things. It was said in a joking tone, so I didn't think she was serious, but looking back I'm not sure that she was really kidding.    

Since then, Sarah's purposely gone places and done things with others in the group without inviting me, while knowing that I was free and wanting to hang out. I told the group that this hurt me, and Sarah replied by complaining that I talk to my boyfriend too much and that I'm not present in the friend group anymore because of him, though the amount that I talk to my BF has actually decreased since my freshman year and nobody had said that it was an issue then.

 I'm no longer close friends with Sarah because I feel like she always needs all of the attention and for things to go her way (among a few other things) and it's starting to splinter my friend group. Nobody else seems to feel that way about her so I don't know if I'm just biased because of how she's treated me since this incident. Because the friendship started crumbling because of this, I want to know, AITA for not inviting her and causing this downfall?

**TL;DR:** I am not a weed smoker, but some of my friends are. Recently, I decided to try it with my boyfriend while my friends were out/busy. One of my friends got mad at me for it. AITA for not inviting her, and for smoking with my boyfriend when my friends assumed I would smoke for the first time with them?
