Okay so a bit of a weird start I know; but I wanted a non-biased persons thoughts on this (or a few people of anyone sees this). I’ll try and keep it brief.(spoiler it isn’t, sorry)

So I want to start of by saying I 21f & my bf 20m currently sort of live together. Technically it’s my flat & he doesn’t contribute to bills but stays here as it’s easier for work and it’s not a small flat.

It started a month or two ago, In a conversation with my boyfriend he stated that he wanted a duo on the video game we both play - I’m often super tired and due to my 8-5 & his 4-9 work schedules we only really get to see each other quite late & I often go to bed pretty quickly. I said straight away that it sounded like a good idea but proffered if it wasn’t a girl. As we both have been known to be taken as flirty by accident, when we didn’t mean to be. (Just very friendly and slightly awkward I guess.) I am also a jealous person admittedly (he is as well though) and just thought I needed to know whether I’m being too harsh. He agreed.

He then a week later said that he had a duo; I asked a few general questions & noticed he said ‘they’ exclusive when referring to them. So I asked & he admitted it was a girl. He claimed they had already added each other previously & got along as friends.

I was immediately upset but said if it just was casual gaming that I couldn’t see an issue.

(Needed backstory) He constantly argues with me over my lack of texting him in the day (I do agree that I am too forgetful & am actively trying to work on this). I am definitely not perfect lol. But then I noticed a female name on his Snapchat & asked who was messaging him at 11pm. He went on to explain that he had asked for this girls Snapchat so they could organise playing together more as he kept his discord notifications turned off. I was even more unhappy with this, which I voiced but was met with accusations of me looking too far into it and not trusting him. But this is where I really want to see if I’m going crazy or not.

Then they start calling for hours every day & messaging - her about how bad her day was and will tell him all about it when they play later, etc - just generally feeling too close. So I told him enough was enough & we spect 3 days fighting about it. The second day ended with him reassuring me it wasn’t like that but could see where I was coming from and we could discuss what to do in the morning. Then he stuck up for her when I made a comment about her having too much time on her hands saying about how she actually worked multiple jobs, etc.

I then because of that being the final straw just cried for hours. I cried myself to sleep and after a little while of staying with me after I crawled into a ball in bed crying he excused himself. I woke up early the next day out of habit for work and had a feeling & looked through his phone.

She had been messaging him asking to play and given up around 2am; he then messaged her at 3am apologising for being late asking if they could please still play. Which they then did for over 2 hours.

I caused a fight and he finally said he saw the error in his ways after I told him to get out.

He has now messaged her on Snapchat after 4 days of no contact to apologise for going AWOL & stating he wouldn’t be playing with her anymore because his girlfriend was upset by it. To which she replied “understandable I would be too”… he then said thanks for taking it so well amongst other little comments, but none as direct as that.

Am I the A if I take this as one final way to make her feel better, like he would love to keep taking but I’m just some insane gf keeping them apart.

(I have omitted a lot of details as I think they just strengthen my case and don’t seem it necessary to rub in.)

What should I do?
