Went out last night with a friend to drink a coffee.. we met with one of her friends which she studied one semester language with.. he's married with a kid back in his country and she has a boyfriend back home the she loves and I feel like she's using him bought her plane tickets, phone, helped her financially with her studies.. and much more... Yesterday during the coffee the guy kept kissing her and putting his hand in her back over her a.. I felt so uncomfortable the thing is with in the same office in a different country and I frankly don't want to be friends with her tbh how can you trust someone like that.. and I don't know how to do it still she's the only person from my country here so it's a bit weird because like it or not it's sometimes good to have to speak with someone who shares your language (easier let's say) I don't know how to act... And yesterday after what I witnessed I kept silent all the way home we took the bus together she asked what's wrong with me I said nothing and she insisted that I'm acting weird.. I don't want to discuss it with her.. I don't care and it's her life and I don't want to be around things like this... So how should I act help plz
