Okayyy.. this can be a bit long but if you can give satisfactory ANSWER to it... it might be very helpful to me... so the situation about me is....
How do you come to know if you are in love?
You are not sure that if you are in love or not (look the person's soul(my friend) is pure, but we think a bit differently at some points/aspects of life) and due to this.. neither you are accepting their proposals or whatever it is... nor you are saying them that you love them (cause you aren't sure, and thus you don't want to play with their feelings), and they are waiting for you to say it cause they have already said it.
There is something you find good to talk, to chat, to spend time with them. A one message from them can change your mood from sad to happy. And if you don't talk to them for some days(2-3), it feels like you have missed a lot of something very big part of your life. You wait (in your leisure or sometimes while doing your routine work) for your night conversations to happen, the whole day. BUT STILL, you don't see them as your future spouse for some unknown reasons.. it might be cause you both are very good at friends level, but some unknown dots seems to be missing due to which you don't take them as your spouse(idk what are those reasons exactly), but friends for the whole life ( I know this friends for the whole life situations will change at some point of them life, but this is what it is.. ) It might also be possible in future that they fall for someone else and will forget/leave you, although they feel the same for you(atleast at current moment of life or even want to you more than you want them), but still.. TILL WHEN someone would wait for you, haha!
Why there is so much of confusion? Why you don't see them as your future spouse if you are in love? Or you are just not in love? And if the situation I told you above is not love, then what it is? And if you are not in love.. then what it is to be in love, how does it feel?
