Remember that it’s okay to cry and grieve for a while. I can’t stress this enough.
My first love was when I was 14 and it was with someone MUCH older (uh oh, I know) so when my parents found out and he was essentially ripped out of my life…it took me about 3 years to actually move on. Why? Because I didn’t grieve. I didn’t actually acknowledge the loss and cry about it. I just forced myself to move on too soon.
Sometimes, people just go right into “rebound” relationships or busy themselves too quickly afterward. Don’t do that. Just take your time and grieve, but then get into activities again when you’re done so the grieving doesn’t turn into moping.
Best of luck.
