<human>: Background - I'm highly unromantic(my SO has mentioned that she is okay with this) and staying in army on weekdays. SO is in uni year 1. We only meet each other on weekends for usual couple stuff like dates. 

SO has a group of friends(3 guys and she's the only girl) that she hangs out with in school everyday. She mainly sticks to this one guy (let's call him alex) even though she's friends with the group of friends. They go to school together most mornings, have meals and classes as well as go back home together. Alex is in a relationship.

I'm scared that things might happen between the two of them - I've asked her to reduce her interactions with him, but she told me that she proclaims he is her best friend(in school) and she needs someone to be with every time. Even when going for their outer social groups they meet first before meeting up with the main group as they live close by each other. Same for going home from the social group.

My SO told me she and Alex are also talking not as much, when they travel to and from uni. They just sit there and use their own ipads. 

Having read alot from this subreddit about how they always claim that 'we're just friends' makes me even more uneasy about this. 

Recently my SO and I have  hit a rough patch in our relationship to the point where we quarrel quite often but still try our best to make it up to each other. This week, she wanted to go for a run at 10pm with Alex and I was not too happy about it. She still went for a run, and vomited. I was worried sick and messaged her alot. After awhile she told me it's only when she's with Alex then I message and show more care - if she cried at home(but stopped and said she was okay and asked me to sleep) I showed much lesser care. I know it's my wrong on this part being too oblivious to such information, but that doesn't allow her to say 'at least someone wants to come out with me at night'.

Can you give me the gist of the text in a nutshell?
<bot>: I feel my so is being too close with another guy and am asking her to keep a distance. Is it too much to ask for?
