You know what, i've been in the exact same position(slightly different) after we broke up, we became very, very close friends and we fell out alot. Yes. We still loved each other, but tbh, we fell out over alot of things, didnt speak to each other for about 2-3 weeks then one of us would say hi or hey etc. and the conversation would get us close again. Dont worry, just wait it out.
