Someone once asked...
Someone answered with kindness...
Seeing your friends be in a relationship because you want to feel happy for them but you may also feel jealous or as if that person has metaphorically stolen your friend or their time when in reality that is just what relationships are like, you make time for the people you love so naturally if you enter a relationship more of your time will go to your partner and therefore less will gp to your friends. However if that relationship is becoming long term and they are doing more things together just by themselves and excluding their friends on both sides you think that they are bad for each other as you need to spend time with someone other than your partner to have a life and not hate each other. So the hardest thing is to watch someone else in a happy relationship and want a relationship but to also not want a relationship and you just have to watch and hate it and be happy for them (totally not a personal story or situation :(
