How to handle loving someone when marriage isn't possible right now?

Assalamu alaikum everyone, I'm facing a dilemma that I'm sure many of us have encountered. What do you do when you care deeply for someone, but due to circumstances like financial stability, education, or family situations, marriage isn't feasible for the next few years? Since getting into a haram relationship isn't an option, how do you manage your feelings without letting them just fade away? There's always the worry that if you don't act, she might choose someone else who is ready. Seeking advice from those who've been in similar situations.
