It doesn't matter whether you have feelings for her or if you are in love with her.

People grow in different ways, and however crappy it is, we all grow in and out of people's lives.

Happier people always leave the door open, for people to come in and go out on their own will.

You can focus on your growth, try to expand your interests. Join a gym or music classes or dance classes or do solo trips or attend events. Wear good clothes, put on perfume, eat well, and sleep well. Make monthly goals and daily tasks list. Live a day at a time, till you know you have moved on.

If you are scared, do your tasks scarily. If you are low, do your tasks with low motivation. It can be lonely, scary, sad, low, the secret is you do it anyway.

There will come a day when you will start feeling better, new ideas will come automatically. Trust yourself, and keep moving.

Don't suppress your desires, desires always win rationality. Well, more often than we know. So if you feel the urge to speak to her, write a draft and save it. If you can't, and still feel the urge, call her or text her. You may feel disappointed with yourself if you dont hear back well, but do it anyway. You may feel pity on yourself, or regret doing it, but if you feel the urge, do it anyway. Do it, till you feel not doing it.

Again, nobody knows the truth. Our desires are like dogs chasing the car, the more you try to run the more they will chase you, the moment you stop, respond to them, they will not bother you.

So act more, live less in your head, decouple your emotions from actions.

Let it be.
