It is said that the emotions a person goes through after being abandoned by a partner are the same as those of a bereavement. Having gone through both myself I can tell you they are not.
After marrying my childhood sweetheart I was widowed after 22 years of marriage & left to raise 2 children. It took me just over a year to get my life back on track.
Fast forward 24 years & after a second marriage I find myself single again, only this time my ex left me for someone else. It''s been nearly 2 years since he left but his lies & betrayal will haunt me for years to come. I won''t go into details about what I went through because we''ve all experienced pretty much the same.
My point is that when a partner dies they don''t choose to but when a partner leaves, they do. The feelings of rejection are the hardest to overcome.
