Oh man… When our crush gets even hotter… Ya, that is though. I know the feeling bro :((
Look into meditation. Learn to meditate properly, there are good books on that. Learn to acknowledge that things are impermanente and unsatisfactory. Try different ways of viewing experience and see which one decreases suffering. When you are feeling badly because of him, look into your thoughts and notice how they dissappear. Does that help? If not, try to widen your experience. Use your sensory doors, hearing, sight, taste, contact. Listen to the sounds and notice what you notice. Same for sight, etc. (Sorry for the rambling, I am into meditation, if that’s not obvious)
Other than that, just keep busy. Find a hobby. Be with your other friends. Make new friends. Join a gym, etc…
The thing I hate about signal is the UI. Everything looks way too big on my device. WhatsApp, for example, holds 2 more chats, and the messages themselves are tidier.
This may seem like it’s not a big deal, but UI is absolutely crucial on order to get people to actually use the app. I moved a few people to signal but they just hated the way it looks. “seems like an app for old people, font too big”. I can see that. They moved back to insta/WhatsApp.
I think some small and easy UI changes could make the app much better: just give us a “compact” mode.
