<human>: Can you condense the text into three sentences or less?

I'm in this situation, and I'm not honestly not sure how I should feel about it. We've been together about 7 months now. She knows he has feelings for her, but she also really values their friendship. That doesn't bother me at all because I trust her. But on the other hand, I don't really know him that well and therefor don't necessarily trust him. How would you feel about this situation?

To add to this, she's been struggling when it comes to friends recently. A lot of her closer friends have moved away leaving her feeling more isolated than she used to be, so she's been valuing the friendships she has even more, recently. I guess that makes this a bit more complicated in my mind.

Also, I feel like if I admit to myself that this makes me uncomfortable, it seems like it would be because I don't trust her. But I know that's not the case. Which makes it hard for me to understand why I would be uncomfortable. Any insights would be really appreciated.
<bot>: My SO is good friends with somebody who has strong feelings for her. I'm not sure how to feel about it.
