What I try to do is not to give any significance to things like those. I try to put up a brave face. Feign ignorance. Pretend I did not see. But people say I look blur when I do that. Because when you ignore you don't have to take action. It's good to ignore potentially bad things but definitely don't ignore the things that you need to take action. What I mean is things that can lead you to sinful behaviours. Things like when someone is obviously flirting with you. You stop yourself from reacting or calling out that behaviour because you don't want to make it awkward and because you are not ready to get into a relationship with anyone at this stage. So I behave in that way, the middle way. A way that says " I like being your friend and a good friend at that but beyond that I leave to Allah and I don't want to have anything now anyways". And I keep asking God to guide me and to help me be strong. Because sometimes, when you love a brother or a sister because of Allah, you don't take action. And that's it. You'll feel better when you do that. Your strength and persistence show how much you love your friend. And if he does not realise it or she, then it's okay, it's fine, you tell youreself, because Allah knows. And that is all that matters.
