I think my friend stole from me and idk what to do
I (19) have a friend (15 turning 16 this year) that I have known for almost three years now. We met through their ex who used to be a very close friend of mine, but things happened and our friendship fell through. My friend (who I'll call just call A) has a troubled life and that is one of the things we've bonded over. A ended up dating someone else and I became friends with their new (now ex) partner. They broke up a few months back and that's that ( except for A has still been contacting my other friend/ their ex even after she just started ignoring them).
Two days ago I went over to A's place to just to hangout. Now, I smoke weed/do edibles. I know my limit and have been open about that in the past to A and have let them hit my (weed) pen maybe once or twice— but they have also just seen my vape and straight up grabbed it before, which has honestly made me uncomfortable. I do not particularly like A smoking/drinking seeing as I know they have used substances to cope in the past and are on heavy medications (+ they are younger than me and I don't feel comfortable supplying minors with drugs). Now before I went to A's house I had packed two gummys in a zip lock bag and put it in my purse. I usually take half a gummy to focus/calm down and then a whole one to truly ease myself (I have really bad anxiety and do not take medication). I did not touch the baggy for the rest of the day.
Once I arrived at A's house I had looked in my bag and the gummys were still there. We had a fun hangout overall and things seemed fine (except for the fact that their ex was brought up a few times). When I got home I was EXHAUSTED and went to bed shortly after getting home. The next morning I checked my bag to 1 clear out any trash, and 2 to grab my gummys and put them back into the container I usually keep them in. But they weren't there. I didn't panic at first, I honestly lose stuff all the time. But later in the day (yesterday) I was on call with a different friend (who I'll call N). I told them what happened and that someone got some nice gummys cause they slipped from my bag... and then I thought about it harder. The way my bag is set up it is litteraly impossible for just ONE thing to fall out of it, if soemthing starts to fall out EVERYTHING falls out. I thought harder, and the only time I left my bag alone (with someone) the whole day was when I went to the bathroom at A's place. N proceeded to tell me that was super weird and I agreed. So I went to A's ex seeing as she's the only person I talk to who also know A super super well, and asked her if she thought it was possible they could've stolen from me, and she said there was a high possibility.
I proceeded to go to A and lay things out (in my opinion) rather politely. I asked if they had gone through my bag and they responded with four hurried messages saying "no, why would I do that?" Four. Messages. They then proceeded to freak out and message me a bunch over trying to find them. Never once did I say I accused them of taking them, I just layed out the fact that I litteraly have Mary Poppins bag and takes A LOT of effort for something to just fall out if it. Maybe half an hour later they called me and said their mom found the gummys on the couch... my purse only made contact with the couch once, if that, before I put it on the coffee table. We sat on the couch the majority of our hangout and I'm pretty sure we would have seen or felt the gummys had they fallen out. But on call they proceeded to say it was rude of me to assume they took them and act as if they did (I never said or even suggested they took them) and that they wanted an apology. They started crying and in the moment I apologized to them but honestly I'm kind of regretting it because... things aren't adding up.
N thinks the entire thing is weird and that A is suspicious as hell. Later on in the day I called A's ex, who is still a good friend of mine, and layed everything out; she also agrees A is acting hella weird and that they probably did take my gummys (they have shop lifted before and have admitted that). I think A took my gummys when I was in the bathroom and forgot about them on the couch where his mom found them the next morning. I'm not mad about the gummys, I'm upset my friend might have stolen from me. I don't want to abandon them, I know what they're going through right now is hard, but I also don't want more stuff to go up missing, you know? Plus A has honestly never been that good of a friend to me. They have done and said things that very clearly upset me in the past and then said a simple sorry and moved on with their day. And before they were with their ex we talked like EVERY DAY (mainly bc we trauma bonded over their ex who was my ex best friend) and I became reliant on them. I've grown and recognized that was bad, but it was really a two way thing with us relying on one another... until them and their most recent ex (my friend) broke things off, in which they've suddenly been more aware that I exist. I don't want them to deal with anymore bullshit but I also don't think I can still be friends with them now that I've realized and processed what they have done in the past + are currently doing.
I'm genuinely at a stand still on this. All my friends are telling me they probably did steal and to just block A, which I think would be the best course of action, but there's also this ache in my gut that says it really could've been a 1/100 chance that the gummys slipped out of my bag... I'm torn between just blocking them or trying to figure out if A really did steal. But I don't think it's worth the distress. I just kind of want an outsiders opinion (despite knowing it'll probably be the same as what my friend's said).
