Coping with a crush while in relationship?

I am in a long term relationship and living with a partner. Stumbled upon a guy that have a crush with for about 4 months, following my partner being unwell and other problems. Maybe it's a form of escapism. I don't know much about my crush and also I have removed myself from any interraction in person to avoid feeling bad. Although I noticed that crush showed curiosity in me and I also followed him on social media which was reciprocated. However we are not exchanging any messages and I have no intention to act upon it as I am a loyal person and cheating is not in my values. Still I feel in pain for everything and it is torturing me. Maybe I need allow more tine like 6 moths to let it cool off. But platonically I am in love for sure. Nothing I can do about it. Well if anyone has been in a similar situation and wanna share, please do, maybe it will help me cope. Tnx.
