Tips for getting over a breakup?

I was with a woman for 15 years. My life revolved around her, I had never lived by myself before I met her, and I didn't even know who I was without her. You've just gotta realize that there's valid reasons that the relationship doesn't work, and accept that it's over. Then stop looking at old pictures, don't text her, don't follow her social media etc. you need time away from her to slowly recover. Avoid self-destructive behavior, and take care of yourself. You will feel normal again eventually.
