Say you dated somebody seriously for a couple years and it had pretty bad ending because of your fault. The other person moved on and became sexual with four people just a month or 2 after your split.. What is normal to feel? What do you do to understand in that situation?
You can't really say what is normal to feel for that situation because different people react differently, sometimes it's hard to understand, they could be sexual with other people just to be sexual active but not anything serious, dating someone for a couple years and then having it end can have a person do things you wouldn't normally think they would, they could be sleeping with other people because they don't trust relationships right now or they are hurt and frustrated it didn't work out with you, too many reasons to really know for sure but I hope everything works out for you
