Reason #1: You make plans for the future WAY TOO SOON.
It can be tricky to gauge how far in the future you can make plans with a new partner. Making plans for the future is always challenging.
I like to abide by a general rule of thumb: never make plans for longer than you’ve been exclusive. So, for example, if you’ve been dating for three months, do not plan anything further into the future than three months.
