Breakups

Hi so me and my ex broke up a month ago because he was too depressed to commit in this relationship.. he still loves me and would check up on me everyday and i do too but lately we’ve been getting really frisky and horny.. is it normal to like satisfy our lust to each other when we’re not in a relationship anymore and we’re not together? I do hope one day he’s okay enough to getback with me but guys is this really okay?
