Leavr before you catch hard feelings,catching feelings hard and letting go is tough,I remember not too long ago when I ended it with a girl,my day wasn't the same anymore.I went through a week of feeling out of place,speaking to her became a habit and having to let her go for good was a big difference.Take time to think about the magnitude of your feelings for him,if they aren't big then assess the situation for anymore red flags and as soon as you see on dip.And if you ever do suffer from heartbreak try and keep yourself as occupied as possible,I played sport and focused more on school,this allowed me to not think about her and eventually all of the feelings faded.
