I would maintain a close bond and friendship with him and see where things go @eloiseanne, hopefully one day he will feel the same way about you Eloise, keep being there for each other and keep going forward, you can do it Eloise, everything will be OK, inbox me anytime if you want to chat or vent, stay strong, you are never alone (hugs)
There’s not much you can do. Neither of you control whom you two have feelings for. I guess- if I were you- I would spend time being friends with him until either he falls in love with somebody else or you do. You could still get to know him as his friend and learn if you really like him or not.
