I've never believed that jumping into bed with another would ease the pain of a broken relationship....most times, it makes it worse. Everyone goes thru pain and sadness, it's life in general.
As for myself, I would remove anything of his, pictures, gifts, etc. Burn them! And have lots of good cries, call my friends and family often for support...force urself to go out shopping or walks. If you've a pet, that does help....Give urself a new make over, hair color, just keeping urself as busy as possible...Even joining a gym....just being outside and around people, no matter how sad you feel....Time is the key! So is patience and repeating that tomorrow will be a better day.
Good Luck!
Now THAT is good advice!
