After a relationship turns sour and divorce/breakup happens, it is normal to suddenly realise a void and try to fill it as soon as possible.
In that emotional volatile state, we might end up making errors by choosing another partner asap because our heart is not in a position to handle that void.
There comes a moment when we realise the error we made. That time, talk to your crush/boyfriend and assert a space; it could be a temporary space. This space/ phase is where a lot of contemplation happens; where one gathers their broken pieces. It is good.
Only after self contemplation do we get a clear picture of what we want in life and understand our priorities.
