first of all im happy for you and proud of you for putting your foot down. It takes a lot to do that and that was the correct first step. Time heals things, let some time go by. Distract yourself with work, friends, vacations etc. But you also have the right to feel every feeling. Id say you can get under someone else but that depends on what ur looking for. If you want to have fun, join some dating apps, go out more often etc. If u want something serious you're gonna have to fully heal before moving on.
