My Birthday

On my first birthday as a single woman I see my ex pulling out of a bar, he said he quit drinking. Well, that ruined it for me, I broke down crying the rest of the night. I feel so ugly and unwanted now. I’m trying to feel worthy but it’s hard when I see him and know he divorced me and is bar hopping. The day he starts dating is gonna be really hard. My daughter says I should get over him he’s not worth my tears, but 16 years of my life I spent loving him. How do I just get over that? Me and my brother going out for my birthday
