I stop thinking about him for a period of time. I swear im over this crush. But then suddenly someone posted a picture of him and my feelings for him come back. What should i do to forget about him?

You should maybe tell him how you feel so that you mind is not curious on the “what if’s” and it will be easier to forget him.

It makes so much sense that seeing a picture would bring feelings to the surface that you had been trying to keep at bay. I know that for me, thinking through my goals and what I want to see happen can help - do you want to pursue this crush? does it feel like it is not right? why might you be hesitant? Those types of questions help me to get too the bottom of my feelings when things feel complicated. Sometimes it can be helpful to talk those things through with someone whom you trust, they can help you to know if the decision you are making is one that feels best for you. You've got this ;)
